Periodic Table

Metal Metalloid Shiny Solid (except Hg) High Melting Point High Density Large Atomic Radii Low ionization Energy Low Electronegativity Malleable/Ductile Good Conductors Shares some characteristics of metal and some of nonmetals Poor Metals Poor Conductors

Alkaline Metals (Family 1) Alkaline Earth Metals (Family 2) Shiny Soft Highly Reactive Low Density Low Melting/Freezing Point Lose 1 Electron Become +1 Cation Shiny Silvery White color Somewhat Reactive Low Density Low Melting/Freezing Point Lose 2 Electrons Become +2 Cation

Family 13 (Boron Family) Family 14 (Carbon Family) Less Reactive Lose 3 Electrons Become +3 Cation B (Boron) Metalloid Al, Ga, In, Ti Poor metals Least Reactive Lose or Gain 4 Electrons Become +4 Cation or -4 Anion C (Carbon) Nonmetal Si, Ge Metalloids Sn, Pb Poor metals

Family 15 (Nitrogen Family) Family 16 (Oxygen Family) Less Reactive Gain 3 Electrons Become -3 Anion N, P Nonmetal As, Sb Metalloids Bi Poor metals Somewhat Reactive Gain 2 Electrons Become -2 Anion O, S, Se Nonmetal Te, Metalloid Po “Metalloid or Poor metal”

Halogen Family (Family 17) Noble Gases (Family 18) Highly Reactive Gain 1 Electron Become -1 Anion Nonmetals except At At Metalloid or Nonmetal Diatomic Molecules Largest Range of states of matter Solid I2, Liquid Br2 Non-Reactive (Inert Gas) Gain 0 Electrons Low Boiling Points High Ionization Energy
