What to do when naming a metal ion
add “ion”
What to do when naming transition metal ions that form >1 ion
Roman numeral in name of metal to indicate charge
What to do when naming a nonmetal
add suffix “ide”
the arrangement of electrons in an atom determines its __________ ___________
chemical properties
building blocks of matter
elements
forces which hold atoms together in chemical compounds
chemical bonds
determines how atoms combine
electron structure
ionic bonds present =
ionic compound
joined through covalent bonds =
molecular compound
what type of bond gives/takes e-
ionic
what type of bond shares e-
covalent
tendency for atoms to lose, gain, or share valence e- so that they can have a noble gas e- structure
octet rule
atom that has lost of gained e-
ion
atoms gain e- = _____ charge
neg -
atoms lose e- = _____ charge
pos +
do metals lose or gain e-
lose e-
do non-metals lose or gain e-
gain e-
group of covalently bonded atoms that have acquired a charge through e- transfer
polyatomic ion
True/False: polyatomic ions always react with other ions to = ionic compounds
True
what makes an ionic compound
metal + non-metal
what makes a covalent compound
non-metal + non-metal
2 types of ionic compounds
fixed-charged
variable-charged
What type of ionic compound:
contains a metal that forms >1 type of positive ion (ex. Fe2+, Fe3+)
variable-charged
What type of ionic compound:
contains a metal that only formed 1 type of positive ion (same charge)
Fixed-charged
Which elements are Fixed-charged
Groups 1A and 2A and Al, Ga, Zn, Cd, Ag
How to name a fixed-charged ionic compound
metal name + stem name of non-metal + -ide
How to name a variable-charged ionic compound
metal name + (Roman numeral) + nonmetal stem name + -ide
