Explain the Law of Conservation of Mass

This states that the total mass of reactants in a chemical reaction always equals the total mass of the products
What is ionic bonding?

This is a force of attraction between oppositely charged ions

It occurs when one atom loses electrons and another atom gains these electrons

If an atom gains an electron the ion is negative

If an atom loses an electron the ion is positive
If an atom gains an electron does the ion become positive or negative?

Negative
If an atom loses an electron does the ion become positive or negative?

Positive
What is covalent bonding?

This is formed when pairs of electrons are shared between two atoms
List the properties of ionic substances

Usually solids

Have high melting and boiling points

Conduct electricity
List the properties of covalent substances

Usually liquid or gases

Have low melting and boiling points

Do not conduct electricity
