Ionic Compounds
An ion made up of a metal and non-metal.
What is a multivalent ion?
An ion that is made up of a transition metal and non-metal.
What is a polyatomic ion?
an ion that is a group of atoms that tend to stay together and carry an overall ionic charge?
How can you tell if a compound is molecular?
Why are Roman numerals not required when naming all types of compounds?
Not all elements can form more than one ion charge.
What is NaBr as a compound name?
Sodium Bromide
Copper (II) Sulfate
What is Mg(ClO3)2 as a compound name?
Magnesium Chlorate
What is CO as a compound name?
Carbon Monoxide

Hydrogen Gas, Oxygen Gas, Fluorine Gas, Liquid Bromine, Solid Iodine, Nitrogen Gas, and Chlorine Gas
Although each ion that makes up an Ionic Compound has a charge, the ionic compound itself is neutral. Explain why?
An Ionic Compound is neutral because the total positive charge is equal to the total negative charge.
What is Copper (II) Nitrate as a formula?
Cu(NO3)2
Why is the chemical formula for Calcium Hydroxide, Ca(OH)2, not written as CaO2H2?
This is because Hydroxide is a single polyatomic ion, not separate oxygen and hydrogen ions.
What is diphosphorus pentasulfide as a formula?
P2S5
What are Valence Shells and Valence Electrons?
The valence shell is the outermost ring in an atom, and the valence electrons are the electrons on it.
