Valency of phosphorus is 3 only.
malkakhaitan13p4wg8u:
sorry you are absolutely wrong
5 is the no. of electrons in the outer most shell
So, the valency is 3
valency means the combining capacity a an atom so 3 is the valency p=2,8,5 it need 3 more electrons to maintain its octet so 3 is the right answer
u r wrong!!
so what is the right answer then
Explanation:
P has 5 electrons in the outer most shell. So in order to be stable it will either loose 5 electrons or gain 3 electrons by following octet rule. Hence it is a non metal and non metals tend to gain electrons.
so P gain 3 electrons to acquire the noble has configuration.
It becomes P^-3 1s^2 2s^2 2p^6 3s^2 3p^6

bro, it also posses valence of 5

HEYA MATE!!
PHOSPHORUS HAS HIGH IONIZATION ENERGY, SO THAT'S WHY IT HAS TO VALENCY, IN WHICH ONE IS NORMAL AS OTHER ATOMS CONTAIN THAT IS 3, WHILE 5 IS DUE TO ITS HIGH IONIZATION ENERGY.
