1 Metals, Non-Metals, Metalloids and the Periodic Table

2 Matter and Elements Matter- anything that has mass and takes up space Element- a pure substance that cannot be broken down into a simpler substance by physical or chemical means

3 Metals Three Categories of Elements Non-metals Metalloids

4 Luster- shiny and reflective Malleable- can be hammered or rolled into flat sheets or other shapes Ductile- can be pulled out or drawn into long wires Metals Reactive- how easily or quickly an element combines with other substances Corrosive- the deterioration (break down) of a metal because of a chemical reaction in the environment Most are solid at room temperature, except Mercury Good Conductors- Thermal Conductivity- the ability of an object to transfer heat Electrical Conductivity- the ability of an object to carry electric current

5 Metal Examples Some examples of metals and their atomic symbols: Copper (Cu) Mercury (Hg) Gold (Au) Potassium (K) Sodium (Na) Silver (Ag)

6 Non-Metals Dull Not malleable/ ductile Poor conductors Reactive At room temperature, most are a solid or gas

7 Non-Metal Examples Some examples of non-metals and their atomic symbols: Oxygen (O) Helium (He) Sulfur (S) Chlorine (Cl) Neon (Ne) Nitrogen (N)

8 Metalloids Have properties of both metals and nonmetals Some are shiny, others dull Some are malleable and ductile Semi-Conductors- substances that can conduct electric current under some conditions but not under other conditions They conduct heat and electricity better than nonmetals, but less than metals. Reactive

9 Metalloid Examples Here are the metalloids and their atomic symbols: Boron (B) Arsenic (As) Silicon (Si) Antimony (Sb) Germanium (Ge) Tellurium (Te) Polonium (Po)

16 Elements are arranged on a chart called Periodic Table the. 1 H Hydrogen Atomic Number Element Symbol Element Name 1 Atomic Mass

17 The Periodic Table A chart that organizes information about the elements Dmitri Mendeleev classified the elements by their properties He wrote the elements on cards with their properties He arranged them according to their atomic masses in rows 100 Greatest Discoveries#3

18 Organization Each horizontal row is a period As you move across a period the atomic numbers increase Each vertical column is called a group or a family Elements in the same group have similar chemical properties or characteristics chemistry/periodictableofelements/
