When an atom with a small amount electrons donates them to an atom with a high amount to make both outer shells full of electrons.

Question 4

Ion

Answer 4

Electrically charged atom.

Question 5

Dissociate

Answer 5

When water molecules force other ionic bonds apart.

Question 6

Electrolyte

Answer 6

Compounds that form ions when dissolved in water.

Question 7
