Structure and Bonding

Bonding between a metal and non-metal. This is becuaes the metal wants a full outer shell.

Doesn't conduct molten ionic compound. Does conduct ionic compound solution.

Metals have delocalised electrons, so electricity can pass through.

Metal ions are arranged in regular layers.

They have an electrostatic force of attraction.

Group 1 = +1

Group 2 = +2

Group 6 = -2

Group 7 = -1

They are found in the nucleus.

Exp. Protons, Neutrons

An element that only exists in pairs.

- giant covalent structure

- each carbon is covaletly bonded to three carbons

- form layers with weak forces between them

- made from carbon

- giant covalent structure

- each carbon is covalently bonded to four carbons

- very strong

- melting point is 3550 degrees

Single - one pair of electrons shared between two atoms

Double - two pairs of electrons shared between two atoms
