Ionic compounds are involved in chemical reactions. What do they consist of?

• Metal and non-metal

• Metal and metals

• Metal and metalloid

• Non-metal and non-metal

For an ionic compound to form in a chemical reaction, the metal must _____________ its valence electrons to the non-metal.

• Maintain and keep

• Share

• Transfer

• Steal

By giving up its electron, the metal becomes a ______________ and the non-metal becomes a _________________.

• positively charged neutron, negatively charge anion

• positively charged anion, negatively charged cation

• positively charged neutron, negatively charged anion

• positively charged cation, negatively charged anion

In an ionic compound formula, which is written first.

• The non-metal is written first, and the metal is written second.

• The metal is written first, and the non-metal is written second.

• It doesn't matter which is written first.

This tells us just how many atoms of that element are found in a compound.

• superscript

• exponent

• subscript

This determines what the subscripts should be when writing an ionic compound.

• charge

• reactivity

• solubilitity

• conductivity

The overall compound must have _________ charge.

• positive

• seven

• negative

• zero
