Atoms make up elements, which combine to form molecules. The mass number is the sum of protons and neutrons in an atom, while the atomic number refers only to the number of protons. Isotopes are variants of the same element that have differing numbers of neutrons. Periodic trends show that atomic size increases down a group, while ionization energy and metallic character decrease across a period.

The Building Blocks of Matter: Discovering the Structure and Properties of Atoms and Molecules in Class 9 Science Chapter 3.Chapter 4
This document discusses the structure of atoms. It begins by defining an atom and outlining Dalton's atomic theory. It then explains that atoms are composed of subatomic particles like electrons, protons, and neutrons. The nucleus contains protons and neutrons, while electrons orbit around the nucleus. Different elements are distinguished by their atomic number, which is the number of protons. Isotopes are atoms that have the same number of protons but different numbers of neutrons. The average atomic mass takes into account the relative abundances of isotopes in a naturally occurring sample of an element.

2 contribution of john dalton martin
John Dalton's atomic theory proposed that all matter is composed of extremely small indivisible particles called atoms. He hypothesized that atoms of the same element are identical, while atoms of different elements differ in their properties. Dalton also suggested that atoms combine in fixed ratios to form compounds. His atomic theory provided an explanation for laws such as the law of conservation of mass and the law of definite proportions. Dalton's experiments helped establish the idea that atoms are the basic building blocks of all matter.
Resumen de science
The history of atomic theory began in 600 BC when Thales discovered static electricity, and Democritus proposed the idea of atoms. In the 1800s, Dalton performed experiments leading to his atomic theory. In the late 1800s and early 1900s, discoveries were made about the electron and structure of the atom, including the nucleus. Elements are made of only one type of atom, while compounds contain different types of atoms joined together. Atoms are the smallest particle that can participate in chemical reactions.
Structure of matter atoms and molecules
- An atom is the smallest particle of an element that retains the chemical properties of that element. All atoms of the same element are identical.
- Atoms are very small, not visible even under a powerful microscope. Models like the ball-and-stick model are used to represent atoms and molecules.
- Atoms consist of even smaller subatomic particles - protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit the nucleus. The number of protons determines the element.

The document provides information about atoms and the structure of matter in three sections:
1. Atoms are the building blocks of matter and consist of protons, neutrons, and electrons. The arrangement of atoms determines the properties of different types of matter.
2. Atoms can combine to form compounds and molecules through chemical bonds. Compounds have unique properties that differ from their constituent elements.
3. Matter exists in four states - solid, liquid, gas, and plasma. The state depends on how tightly or freely the atoms and molecules are able to move. Solids have a fixed structure while gases spread freely.

An atom is the smallest particle of an element that retains the chemical properties of that element. Atoms themselves are made up of even smaller particles called subatomic particles, which include protons, neutrons, and electrons. Protons and neutrons are found in the center of the atom in the nucleus, while electrons orbit around the outside of the nucleus. The number of protons in the nucleus determines which element an atom is, while the number of neutrons can vary between atoms of the same element.
The atom
The document discusses key scientists who contributed to atomic theory, including J.J. Thomson, Marie and Pierre Curie, Ernest Rutherford, and Niels Bohr. It also covers atomic structure, isotopes, electron configuration, and orbital shapes. Atoms are made up of a nucleus surrounded by electrons, with most of the atom being empty space. The relative atomic mass is a measure of the average mass of an element's isotopes.
Structure of atoms10
Scientists have been studying atoms since the 1800s using models to understand their structure and behavior. Early philosophers proposed the idea of atoms, while scientists like Dalton, Thomson, Rutherford, and Bohr developed atomic models through experiments. They discovered that atoms are mostly empty space with a small, dense nucleus at the center containing protons and neutrons, and electrons orbiting the nucleus. The number of protons determines the element, while isotopes of an element have different numbers of neutrons.
History-of-Atom-Model.pptx
The ancient Greek philosophers Leucippus and Democritus first proposed the atomic theory in the 5th century BC. They believed that all matter is composed of indivisible atoms moving through empty space, and that different kinds of atoms exist which give matter its properties. John Dalton later expanded on this theory in the 19th century, stating that atoms are indivisible, indestructible particles that do not change during chemical reactions. J.J. Thomson's discovery of the electron led to the "plum pudding" atomic model, with electrons distributed throughout a sphere of positive charge. Ernest Rutherford then proposed the nuclear model of the atom as a tiny dense nucleus surrounded by orbiting electrons.

Weaning from mechanical ventilation should be considered when the disease prompting intubation has improved and daily screening for weaning potential is performed. Studies show most intubated patients should have scheduled spontaneous breathing trials following daily sedation breaks. For SBT, the patient must be alert, able to follow commands and breathe spontaneously, with stable oxygenation and hemodynamics before extubation. Daily SBT involves at least 30-120 minutes of breathing without ventilator support using an open breathing circuit or minimal pressure support. A successful SBT is when the patient can breathe without distress and their vital signs remain stable.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

A element is composed of one type of atom while elements combine with each other to form molecules.2. It is important to learn the history of scientific discoveries, because it provides insights into how to make ethical choices related to science.3.The mass number is the sum of protons and neutrons while the atomic number is only the number of protons. The atomic number is also found on the periodic number.4. The atomic mass is determined by adding protons and neutrons. Isotropes are members of a family of an element that have the same number of protons but different number of neutrons.5. The 4 periodic trends discussed are ionization energy, atomic size, and metallic character. The atomic size increases from top to bottom, ionization energy decreases from going down, and metallic character decreases going from left to right.
