Isotopes

Atoms of the same element with different amounts of neutrons and therefore different atomic masses

Ions

When a atom’s number of electrons do not equal the number of protons, therefore it will have a positive or negative charge

If I changed the number of Neutrons:

Isotopes are created

If I changed the number of Electrons:

Ions are created

If I changed the number of Protons:

Element changes

Ionic Bonding

The electrostatic force of attraction between positively charged metal ions and negatively charged non-metal ions.

Covalent Bonding

The electrostatic force of attraction between a shared pair of electrons and the positive nuclei of it’s atoms

Mass Number
