Back 21

Ion

Front 22

This is the numerical value of the electric charge with a plus or minus sign.

Back 22

Empirical formula

Front 27

This is a chemical formula that indicates the number and type of atoms in one molecule

Back 27

A molecular formula

Front 28

These are compounds formed by the combination of two or more atoms held together by covalent bonds.

Front 41

These are neutral particles that have about the same mass as protons.

Back 41

Neutrons

Front 42

These are negatively charged particles with almost no mass that orbit the nucleus.

Back 42

Electrons

Front 43

The number of electrons in an atom must be equal to
