Mar 21, 2012 · The formation of covalent bonds producing noble gas structures is quite common. When atoms bond covalently, they often produce outer electronic structures the same as noble gases-full outer shell. This is so they become stable and unreactive. The more electrons shared, the more covalent bonds there are, the more stable the molecule is.

Oct 10, 2013 · A simple lesson: Hand out molymod kits and get the pupils to select the correct atoms and bond them together. They'll soon realise that Carbon needs to form 4 bonds.... etc. If you go through a few examples of how to draw covalent bonding diagrams, it should be pretty straight forward. I&'ve also attached some past exam questions to use as a hw ...
8. What happens to electrons in covalent bonding? (a) They are shared by the atoms (b) They pass from one atom to another (c) They are removed from the atoms’ shell (d) They are added to both atoms’ shells. 9. A substance with a pH of 6 is: (a) a weak acid (b)a strong acid (c) a weak alkali (d) neutral. 10.
