12/02/14 Be prepared to discuss last nights homework! Periodic Table The periodic table is a chart of the elements arranged into rows and columns according to their physical and chemical properties. Elements are grouped together

by their similarities in properties and trends. Dimitri Mendeleev Dimitri Mendeleev was a Russian chemist who created the earliest periodic table. He arranged the elements in a list using their atomic masses and found that the properties of the elements repeated in a pattern. He used this table to predict the properties of elements that were not discovered yet.

Periodic means repeating pattern. Periodic Table Basics Rows on the periodic table are called periods. Columns on the periodic table are called groups or families or groups. Each individual element has an atomic number. This is the number of protons that the atom of this element has. As you move from left to right, and top to bottom, the atomic number and the atomic mass increases.

The Periodic Table of Elements Atomic number increases! Atomic mass increases! The Periodic Table of Elements Atomic mass increases! The Periodic Table of Elements

Number of valence electrons Electrons in the outermost energy level! Reading an Elements Square How do I find # of protons = atomic number # of electrons = atomic number *in a neutral atom*

# of neutrons = mass number - atomic number *round the mass number to the nearest whole number* Using the Periodic Table Metals, Nonmetals, Metalloids The Periodic Table The periodic table is sorted by similarities in

properties There are three main categories on the periodic table: metals, nonmetals, and metalloids. These categories are broken up into smaller families with more specific properties. (Alkali

metals, Halogens, Noble Gases, etc.) Today were going to look at the 3 main categories and the properties that they share. Metals Have luster (shiny) Malleable and ductile High densities and high melting points

Good conductors of electricity, but poor insulators Most are solids Examples of families: alkali metals and alkaline earth metals are very reactive. Nonmetals Have no luster Brittle Good insulators, but poor conductors of electricity

Most are gases The elements that make up life are nonmetals (carbon, oxygen, hydrogen) Examples of families: Halogens: Very reactive Noble gases: Nonreactive or inert Metalloids Have properties of

metals and nonmetals Semiconductors: conducts electricity at high temperature, insulates at low temperatures Used in electronic devices Example: Silicon is the most abundant

metalloid. Foldable Cutouts Open your textbooks to pg 348-349. Fill in all atomic numbers and atomic masses for each element on your sheet. Then, cut out each element square. Use the textbook to help you sort each element in their correct category in your foldable(metal, nonmetal, metalloid).
