Qi Ying asked: how many bonds does chlorine and hydrogen have?
my reply:
Chlorine and hydrogen does not have bonds. The question 'should be' how many electrons can the hydrogen and chlorine used for bonding.
Chlorine is in Group 7 so it has 7 electrons.
If it combines with a metal group, then it can only accept 1 electron from the metal. ( so that add up to be 8 electrons )
If it combines with a non-metal group, then it can share only 1 electron from the non-metal thus forming 8 electrons too.
In this case, if chlorine combines with hydrogen to form hydrogen chloride, then only 1 bond is formed between hydrogen and chlorine.
ms pang :)
