ionic bonding notes

Ionization Energy

The energy required to remove an electron from an atom.

Electronegativity

The tendency of an atom to attract electrons towards itself.

Octet Rule

The principle that atoms tend to gain, lose, or share electrons to have eight valence electrons, achieving stability.

Lewis Dot Structure

A diagram that shows the valence electrons of an atom and how they are arranged in covalent bonds.

Criss Cross Method

A technique for determining the formula of an ionic compound by using the charges of the elements.

Cation

A positively charged ion, typically a metal.

Anion

A negatively charged ion, typically a non-metal.

Naming Polyatomic Ions

The process of naming ions that consist of multiple atoms, where the cation is named first followed by the anion.

Transition Metal

Elements that have partially filled d-orbitals and often require a Roman numeral to indicate their charge in compounds.

Example of Naming

When naming Manganese (II) Nitride, the (II) indicates the charge of the manganese ion.
