Answer:
Group 15 elements are also called Nitrogen family includes nitrogen phosphorus, arsenic, antimony and bismuth elements. The p-block elements are also known as the Representative Elements which is placed on the right side of the main periodic table.
Explanation:
The p-block elements are put to the right-hand side of the periodic table in groups from 13 to 18. In the iotas of p-block elements, the separating electron enters the valence p subshell. In this manner, in these elements, the n p subshell is step by step filled.
The general valence shell electronic setup of group fifteen elements is ns2, np1-6. The electronic design of helium is 1s2. Disregarding the way that helium does not have p orbitals, it is a p-block element since it takes after that of other p-block elements of the eighteenth group concerning their physical and compound properties. P-block elements are generally non-metals, while the remaining are metalloids and metals.
