Here are the answers to my last blog, 27th July 2012
The electron arrangements of sodium and chlorine are as follows:
Na 2,8,1 Cl 2,8,7
When sodium reacts with chlorine the outer electron from sodium is transferred to the outer electron shell of chlorine.
Two ions are formed during the reaction (transfer process), Na+ and Cl-.
The electron arrangements of the two ions are:
Na+ 2,8 Cl- 2,8,8
So which members of the nobility do the two ions copy with their electron arrangements?
