The following compounds and the number and type of ions are as follows:
Gold and chloride:
Gold (III) = Au 3+
Chloride = Cl 1-
Calcium and Sulfate:
Calcium Sulfate:
Calcium = Ca 2+
Sulfate = SO4 2-
Magnesium and Hydroxide
Magnesium Hydroxide: Mg(OH)2
Magnesium: Mg 2+
Hydroxide: (OH) 1-
The answer should be B, ionic bond.
Ionic bond is the bonding between a metal and a non-metal. While covalent bond is the bond between non-metals, and metallic bond is the bond between metals.
Since Na, sodium, is a metal, and Cl, chlorine, is a non-metal, the bond formed between them is an ionic bond. Sodium gives up an electron to chlorine inside this bonding.
