What does a binary ionic compound consist of?
2 monoatomic ions
Which types of elements tend to form ionic compounds?
Metals and nonmetals
Which types of elements tend to form covalent compounds?
Nonmetals with each other
What is ZnBr2
Zinc bromide. This is an ionic compound because it combines a metal with a nonmetal.
What is the empirical formula for copper (II) oxide?

What is the prefix for 6 atoms in a binary covalent compound?
Hexa
What is the prefix for 7 atoms in a binary covalent compound?
Hepta
What is N2O4
Dinitrogen tetroxide. This is a covalent compound (molecule) because it’s between 2 nonmetals
What is a binary acid solution?
The product of gas compounds dissolving in water.
How do you name a binary acid solution?
- Prefix hydro
- Anion nonmetal root
- Suffix -ic and acid
HCl = hydrochloric acid
What are oxacids?
Compounds with hydrogen and an oxoanion.
How do you name oxacids?
The -ate in the anion becomes -ic
The -ite in the anion becomes -ous
HBrO4 = perbromic acid, HBrO2 = bromous acid
