Ionic Bonds

These are all chemical FORMULAS that represent molecules

Ionic Bonding happens when an atom GIVES 1 or more Valence Electrons away to another atom who then GAINS 1 or more Valence Electrons

OCTET Rule: Every atom is unstable.

For an atom to become stable they need 8 Valence Electrons.

They complete this task by giving away or receiving electrons.

The METAL atom gives away electrons

The NONMETAL atom receives the electrons

When an ATOM gains an ELECTRON it becomes NEGATIVELY CHARGED

When an ATOM loses an ELECTRON it becomes POSITIVELY CHARGED

Atoms that lose electrons become Positively Charged and are called CATIONS

Atoms that GAIN electrons become NEGATIVELY Charged and called Anions

Metals give away electrons become cations

Non metals gain electrons become anions

When atoms lose or gain electrons they become charged and turn into IONS

Opposite charges attract one another and is what BONDS atoms together to form molecules

Every ATOM is trying to fill their OCTET (8 valence electrons)
