1

amu (atomic mass unit)

1/12 mass of 12 C atoms, very close to the mass of one proton or neutron but not exactly

2

mole =

6.022 times 10 to the 23rd molecules

3

noble gases

don't want anymore and don't develop any other charge

4

halogen

develop (-1) charge

5

alkali and alkali metals

want to loose electrons (+1 or +2)

6

transition metals

nothing

7

type 1

cations (metals) and anions (nonmetals) IONIC, say the cation then anion and add (-ide)

8

type 2

BINARY IONS, IONIC COMPOUNDS transition metal (that varies in charge) and nonmetal, say cation and its charge (roman numeral) then anion and add (-ide), contain metals that can form more than one type of cation

9

molar mass

mass in grams of one moelcule of compound, obtained by summing the masses of compment atoms

10

type 3

BINARY COVALENT COMPOUNDS, 2 non-metals, (the first is the fathest to the left and or down listed first, the second element you ad ide), PREFIXES, can't use charges on periodic table group

11

type 4

IONIC COMPOUND WITH POLYATOMIC ION), metal (cation) with polyatomic ions
