Unit 3#1 Flashcards
amu (atomic mass unit)
1/12 mass of 12 C atoms, very close to the mass of one proton or neutron but not exactly
mole =
6.022 times 10 to the 23rd molecules
noble gases
don’t want anymore and don’t develop any other charge
halogen
develop (-1) charge
alkali and alkali metals
want to loose electrons (+1 or +2)
transition metals
nothing
type 1
cations (metals) and anions (nonmetals) IONIC, say the cation then anion and add (-ide)
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
molar mass
mass in grams of one moelcule of compound, obtained by summing the masses of compment atoms
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
type 4
IONIC COMPOUND WITH POLYATOMIC ION), metal (cation) with polyatomic ions
type 4 exceptions
zinc is always 2+ and silver is always 1+
acids
anything that start with Hydrogen
formula for sodium salt
replace hydrogen with sodium
