Why is the size of neon greater than fluorine?
Advertisements
उत्तर
The size of Neon is bigger compared to fluorine because the outer shell of neon is complete (octet). As a result, the effect of nuclear pull over the valence shell electrons cannot be seen. Hence the size of Neon is greater than fluorine.
