Ionic Bonding

Valence Electrons

Electrons in the outer most energy level of an atom.

Metals

These tend to lose electrons and are generally located on the left side of the periodic table.

Non-metals

These tend to gain electrons and are generally located on the right side of the periodic table.

Ionic bond

This bond occurs between a metal and a nonmetal. It occurs when one or more electrons transfer from one atom to another.

Symbol

The one or two letter abbreviation for an element.

Chemical Formula

Contains symbols and subscripts and tells us what type of atom and how many atom the compound is made of.

Compound

This forms when two or more elements bond to each other.

Ion

An atom or molecule with a charge because it has lost or gained electrons.

Electron dot diagram

This diagram is used as a represent the outermost electrons (valence electrons) in an element.

Cation

An ion with a positive charge

Anion

An ion with a negative charge

Octet

A full outer energy level with 8 electrons.

Subscript

Found in the lower right of a chemical formula. This tells us how many of each atom are in a compound.

+1

Group 1 elements will form an ion of this amount of charge.

+2

Group 2 elements will form an ion of this amount of charge.

+3

Group 13 elements will form an ion of this amount of charge.

-1

Group 17 elements will form an ion of this amount of charge.

-2

Group 16 elements will form an ion of this amount of charge.

-3

Group 17 elements will form an ion of this amount of charge.

-ide

The suffix added to an anion's name

Superscript

Found in the upper right of the ion symbol. This tells us the charge of the ion.
