Q1. Phosphorus is important in DNA and energy carriers in biology but for the periodic table alone phosphorus P is most typically placed in which group in modern numbering?
Answer: Group 15
Explanation: Phosphorus (P) belongs to Group 15 of the modern periodic table, a group also known as the pnictogens, which includes nitrogen, arsenic, antimony, and bismuth. Its five valence electrons allow it to form the phosphate groups essential in DNA backbones and in ATP, the cell's main energy currency.
