the nature of bonds

what is the nature of ionic bonding?

electrostatic attraction between positive and negative ions

explain the strengths of ionic bonding

the smaller the ion and the greater the charge on the ion, the stronger the ionic bonding

what is the nature of covalent bonding?

shared pair of electrons between atoms (normally between 2 non-metals)

which structures have covalent bonding?

• simple molecular

• giant covalent

explain the strength of covalent bonding

• the shorter the bond, the stronger

• double bonds stronger than single, triple stronger than double

what is the nature of metallic bonding?

attraction between the positive nuclei of the metal atoms and the negative delocalised outer shell electrons

explain the strength of metallic bonding

the smaller the atoms and the more delocalised electrons, the stronger the bond
