Ionic Bonding

Ionic bond forms between metals and non-metals.This gives the bonded atoms an electric charge.

Basically, ionic bonding is the transfer of electrons between a metal and non-metal. This is due to the fact that atoms always take the easiest way to fill their outer shell of electrons to ensure stability in both atoms.

An example is the ionic bonding of chlorine and sodium. In this case, an electron from the outer shell of the sodium atom is being given to the chlorine atom. this way, the outer shells of both atoms are filled. The electrostatic attraction sticks the ions together.

Note: Metal always forms positive ions while non-metals form negative ions

Properties of ionic compounds:1. Made of crystals(which can be split along certain angles)2. Have high melting points3. Are often soluble in water 4. Conducts eletricity when molten or aqueous, not when solid.( because ions have to be able to move around freely to conduct electricity and not remain in a fixed position.)
