The document discusses the structure of atoms. It explains that atoms have two main parts - a nucleus at the center made up of protons and neutrons, and electrons that orbit around the nucleus. The nucleus is positively charged due to the protons, while the electrons are negatively charged. Together, the positive and negative charges balance each other out, giving the overall atom a net neutral charge. Diagrams are provided showing different ways atoms can be drawn to represent these components.

All matter is made up of atoms, which are composed of subatomic particles including electrons, protons, and neutrons. Atoms are mostly empty space with a dense nucleus at the center containing protons and neutrons. Electrons orbit the nucleus in shells or orbitals. Atoms can form ions by gaining or losing electrons, becoming positively or negatively charged. Multiple atoms can bond together to form molecules or crystalline solids, and compounds are made of different types of atoms chemically bonded together.

Mariana Serrato

The document discusses the basic structure and composition of atoms. Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus. Though atoms are small, they are the fundamental unit that makes up all matter. The number of protons determines the element, while the number of neutrons can vary forming isotopes of that element. The periodic table organizes the known elements based on their chemical and physical properties.

Electricity and magnetism

anaruperez

Electricity and magnetism are explained through the movement of electrons. Atoms are made up of protons, neutrons, and electrons. Electrons can move along a wire due to positive and negative charges. Static electricity is created through friction that changes the number of electrons on objects. Magnets have magnetic fields and poles that attract or repel other magnets or metals. The Earth has a magnetic field created by its liquid iron core that protects us with its magnetosphere.

Bohr's model

Sidra Javed

1) Bohr's atomic model successfully explained the hydrogen spectrum by postulating that electrons revolve in definite orbits called energy levels without radiating energy. 2) The radius, energy, and frequency of radiation emitted by electrons in different orbits were derived based on Bohr's model. 3) Bohr's model showed that electrons can jump between discrete energy levels, emitting or absorbing photons of specific frequencies corresponding to the energy differences between levels.

This document discusses the development of atomic models from ancient Greek ideas to Rutherford's gold foil experiment and Bohr's model of the hydrogen atom. It introduces Dalton's atomic theory and developments like the plum pudding model, discovery of the electron, Rutherford's nuclear model, and Bohr's explanation of emission spectra. Key concepts covered include atomic structure, isotopes, atomic notation, and forces that hold the nucleus together.

What is electricity

DrSarahAyoub

Electricity is related to the structure and properties of atoms. Atoms are the smallest particle that matter can be divided into, consisting of a nucleus with positively charged protons and neutral neutrons surrounded by negatively charged electrons in energy levels. The attraction between the positive nucleus and negative electrons holds the atom together in a neutral state. Static electricity and lightning occur when an imbalance of charges develops, such as rubbing objects together to transfer electrons or friction separating charges within storm clouds.

GilbertAman

This document defines static electricity and electric charges. It explains that atoms become charged when they gain or lose electrons, making them more positive or negative. Electrons can be easily removed from atoms, while protons are very difficult to remove. Charging occurs through friction, contact, or induction as electrons are transferred between objects. Conductors allow charge to spread evenly, while insulators trap charges on their surface. Grounding neutralizes charged objects by allowing electrons to flow to or from the earth.

Structure of atomic

Poonam Singh

All matter is composed of atoms. Atoms are composed of protons, neutrons, and electrons. Rutherford's gold foil experiment disproved the plum pudding model of the atom and led to the discovery of the nuclear atom, with a small, dense nucleus surrounded by electrons. Niels Bohr refined this model by suggesting that electrons orbit the nucleus in discrete energy levels. When electrons change orbits, electromagnetic radiation is emitted or absorbed at wavelengths specific to each element.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...

indexPub

The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Wound healing PPT

Jyoti Chand

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications. A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function. Healing is the body’s response to injury in an attempt to restore normal structure and functions. Healing can occur in two ways: Regeneration and Repair There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc. Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
