9 Covalent bonding The sharing of electrons

10 Covalent bonding is directional. The strength of the bond is in one direction Covalent structures are low melting point solid, liquids and gases They tend not to be soluble in water and have poor electrical conductivity

12 The outer shell of hydrogen can only contain a max of two electrons (1s orbital) The electrons are equally shared between the hydrogen's

13 Oxygen

14 Nitrogen

15 Hydrogen fluoride ammonia

16 Ethene C 2 H 4

17 Carbon dioxide

18 Element Bonds HOSNCPHOSNCP Number of electrons in the outer shell

21 Dative Bonding A covalent bond forms when both electrons come from the same atom

22 Carbon monoxide
