Chemical nomenclature

molecular compounds

a prefix is used to indicate the # of atoms

when there's only one of the first element you ignore the prefix

when there's only one of the second element the prefix is -mono

names of covalent bond

single

double

triple

non metals bond with other non metals

non-metals in molecular compounds have to share electrons.

they also create a covalent bond when electrons are shared

polyatomic bonding

polyatomic anion contain oxygen

when there's 2 oxyanions formed in one element the one with more oxygen the name ends in -ate and the one with less oxygen ends with -ite

also known as a radical bond with metal to form ionic compounds

you have to know the charge of the ions

ionic compounds

when giving your compounds names the first symbol you would use the cation

aka the non-metal would use the root of the anion and add -ide

the -ide ending is placed at the end of a monoatomic anion

which involve obtaining a complete outer valence shell

having a charge of 0
