The five properties of an ionic compound.
What is 1) high melting point, 2) high boiling point, 3) crystalline, 4) hard & brittle, 5) conducts electricity when melted or dissolved in water?
Sodium Oxide
What is Na2O
The name of the compound with the formula MgSO4.
What is magnesium sulfate?
The formula that represents Strontium Nitrate.
What is Sr(NO3)2?
As a sodium atom forms a sodium ion, the number of protons in its nucleus: decreases, increases, or stays the same.
What is stays the same? PROTONS DO NOT EVER CHANGE. If you change the protons you change the element/atom.
