English Class: The Periodic Table
The document discusses the importance and history of the periodic table. It was created by Dmitri Mendeleev to organize the known elements according to increasing atomic weight and how they react. The periodic table groups elements into columns called families that share similar properties. It provides information on important families including hydrogen, alkali metals, alkaline earth metals, transition metals, and noble gases. The periodic table is a fundamental tool for chemists to understand the elements.
Group Names and Properties
Groups are columns on the periodic table that contain elements with the same number of valence electrons. The document discusses several important groups including hydrogen, alkali metals, alkaline earth metals, transition metals, boron family, carbon family, nitrogen family, oxygen family, halogens, and noble gases. It provides key details about the location of each group on the periodic table and chemical properties common to the elements within each group.
Periodic table
The periodic table organizes the elements and provides useful information to chemists. It was developed by Dmitri Mendeleev in the late 1800s by arranging elements in rows by atomic weight and columns by chemical properties. The modern periodic table arranges elements by atomic number and divides them into groups and periods that predict chemical and physical trends. The position of an element on the periodic table reveals its valence electrons and how it will bond and react.
Periodic table 2
The document discusses the organization and properties of the periodic table. It is divided into 18 columns of elements grouped by similar properties. Rows represent periods where properties change gradually. Most elements in groups 3-12 are metals that are solids with high melting points, good conductivity, and form positive ions. Nonmetals in groups 13-18 are usually gases or brittle solids with low conductivity and form negative ions. Some elements have mixed metal and nonmetal properties.
Periodic table
The periodic table was created by Russian chemist Dimitri Mendeleev in 1869 to show the repeating patterns of elements. It arranges the known chemical elements in an 18 column by 7 row grid based on their atomic structure and properties. Elements are organized by increasing atomic number, with similar elements grouped together, allowing scientists to predict properties of unknown elements and new discoveries.
Basics of periodic table
Dmitri Mendeleev organized the periodic table into groups and periods based on the properties of elements. Elements are categorized as metals or non-metals, with non-metals including metalloids, other nonmetals, halogens and noble gases. Metals include alkali metals, alkaline earth metals, lanthanoids, actinoids and transitional metals. The periodic table provides information on common elements like hydrogen, oxygen, and helium.
11/7/11
The document provides instruction on classifying elements on the periodic table. It explains that the periodic table is organized into groups that run vertically and periods that run horizontally. Elements are classified as metals, nonmetals, metalloids, halogens, or noble gases based on their location on the periodic table. Metals are mostly on the left, nonmetals are mostly on the right, metalloids are in between, halogens are in group 17, and noble gases are in group 18. Students then practice identifying groups and periods for elements and classifying different elements.

The document discusses the key elements of the periodic table including atomic number, atomic mass, and how elements are arranged. It summarizes the contributions of Dmitri Mendeleev and Henry Moseley. Mendeleev arranged elements based on atomic mass and left gaps for undiscovered elements. Moseley discovered that atomic number is fundamental. The periodic table is arranged into periods and groups with metals, nonmetals and metalloids. Different groups of elements are discussed including alkali metals, alkaline earth metals, halogens, and noble gases. Examples are given of elements and their properties.

The Periodic Table
The document summarizes key aspects of the periodic table. It describes how the periodic table is organized into rows called periods and columns called families or groups. Elements in the same group have similar properties. Metals are on the left and center of the table, while non-metals are on the right. Metalloids separate metals and non-metals. Chemical families have elements with similar properties, such as alkali metals in Group 1 reacting easily with water and air. The number of valence electrons increases from left to right across a period and decreases down a group.

Element Classification
This document discusses the classification and properties of elements according to their position on the periodic table. It describes the three main groups of elements - metals, nonmetals, and metalloids. Metals are shiny, conductive, malleable, and lose electrons to form positive ions. Nonmetals are dull, poor conductors, brittle, and gain electrons to form negative ions. Metalloids have some properties of both metals and nonmetals. Within these groups, elements are further classified based on their specific properties, such as alkali metals being very reactive and noble gases being stable and unreactive. Hydrogen and helium are also discussed as having unique behaviors compared to other elements.

The periodic table is a chart that arranges the elements in rows and columns according to their physical and chemical properties. Elements in the same group have similar properties, and an element's location on the periodic table provides information about its properties. Metals are generally located on the left side and middle of the periodic table and have properties such as conductivity and luster, while nonmetals are usually gases or brittle solids found on the right side. Metalloids exhibit some properties of both metals and nonmetals.

- 2. Elements may be classified (put into sets) in One way : • metals or non-metals (conductors or non-conductors) Chemists classify elements by arranging them in the Periodic Table. In a group, all the elements present have similar chemical properties. Group I (1) – the Alkali Metals All of the elements in Group I are metals. They are soft and easily cut. When freshly cut they have a bright, shiny, silvery appearance. All react vigorously with air and water so are stored under oil. Solutions of their compounds are alkaline in nature. They become more reactive going down the Periodic Table.
