Unit 5 -Write Chemical Formulas and Name Compounds

if the binary formulas start is from groups 1,2, 13, and Ag and Zn then what type is it

type 1

if the binary formulas start is from groups 3-12 and 14 then what type is it

type 2

what is a covalent compound

two nonmetals bonded

what is a ionic compound

one metal and one nonmetal

what number system do we use for type 2

roman numerals

which type requires you to write down the charge

type 2

if there is more than one polyatomic ion then what needs to be around it?

parentheses

nonmetals are the what

anions

metals are the what

cations

the number of electrons donated must equal what

the number of electrons accepted

the positive and negative charges must equal what when added

0

what are the two exceptions that are type 1 but would normally be type 2

silver (Ag) and zinc (Zn)

the prefix hydro is used when naming which type of acid is it

acids without oxygen

if the formula starts with H then it is a what

an acid

if the formula starts with a nonmetal then what type is it

type 3

if the formula starts with a metal what types can it be

types 1,2 and 4

if the formula starts with a metal and is binary what types can it be

types 1 and 2

prefixes tell what

how many of an element

if the acid ends in ate then what does it change to

ic

if the acid ends in ite then what does it change to

ous

type 3 needs a what at the front of the second element

prefix

if the bond is covalent then it has no what

no charge
