Group Names Alkali metals- first family Alkaline Earth- second family Transition metals-columns in middle over to stair case Halogens Noble gases Actinides and Lanthanides
General Characteristics Metals- left of stair case, positive charge, ionic bonding. Nonmetals- right of stairs, negative or slightly positive charge, covalent bonding. Metalloids- on the stairs, characteristics of metals and nonmetals. Electron configuration- s, p, d, f blocks
Periodic Trends Radius- decreases going left to right. Increases going down. Electronegativity- (desire for electrons), increases left to right, decreases going down. Ionization energy- (the energy needed to remove the outer electron) increases left to right.
Information on the Periodic Table General Characteristics Atomic Number (protons) Average Atomic Mass (protons + neutrons) Oxidation Number (charge(s)) Melting and Boiling Points Electron Configuration State- solid, liquid, aqueous, gas Radioactive, synthetic
