Question
Explain
Octet rule for the formation of sodium chloride
Advertisements
Solution
Elements tend to combine with one another to attain the stable electronic configuration of the nearest inert gas.
Sodium chloride
The sodium atom has 1 electron in the valence shell which it donates to the chlorine atom with 7 electrons in the valence shell to attain the stable electronic configuration of the nearest inert gas, i.e. 8 electrons in the valence shell. This is known as the octet rule. These elements combine to form sodium chloride.
