Configuration of `5p^(1)` is

The electronic configuration of P (Z=15) is 2, 8, 5, why is the valency of phosphorus is 3 and not 5 ?

In the long form of the periodic table the valence shell electronic configuration of 5s^(2)5p^(4) corresponds to the element present in:

In the long form of the periodic table the valence shell electronic configuration of 5s^(2)5p^(4) corresponds to the element present in:

In the long form of the periodic table, the valence shell electronic configuration of 5s^(2) 5p^(4) corresponds to the element present in:

The configuration of 1s^(2)2s^(2)2p^(5)3s^(1) shows

An element A has the configuration 1s^(2)2s^(2)//2p^(6)3s^(1) and the elemen B has the configuration 1s^(2)2s^(2)2p^(4) Give the formula of the compound formed. 1s^(2)2s^(2)2p^(6)3s^(1) while the configuration of B is 1s^(2)2s^(2)2p^(5). What type of bond is likely to be formed between them ?

The valency shell electron configuration of an atom is 4s^(2)4p^(5) . The maximum no of electron having parallel spin in this configuration are
