Chemical Bonding

Compound

A substance that is made up of two or more different elements combined together chemically

Transition Metal

A metal that forms at least one ion with a partially filled d sublvel.

Octet Rule

When bonding occurs, atoms tend to reach an electron arrangment with 8 electrons in their outer shell/energy level

Ion

An atom that has gained or lost and electron

Ionic Bonds

The force of attraction between oppositely charged ions, always forme by the complete transfer of electrons

Group 1 and 2 tend to lose an electron making it a posotive charge.

Group 6 and 7 tend to gain an electron making it a negative charge.

Valence Electrons

The electrons in the outermost shell

Lewis diagrams

Used to showe ionic bonds. Only draw the valent shell.

Ionic copounds

Are neutral in charge. There is and equal number of positive and negative charges.
