Question

Atomic number of the element of VA group, coming after nitrogen is

• A. 7
• B. 15
• C. 14
• D. 17

Answer 1

The Correct Option is B

To solve the problem of identifying the atomic number of the element in the VA group that comes after nitrogen, we begin with understanding the periodic table groups. 

The nitrogen group, also known as group 15 or VA, includes nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). The elements in this group share similar properties, such as forming -3 charges, due to having five valence electrons.

Nitrogen (N) is the first element in this group, with an atomic number of 7. The subsequent element in the VA group is phosphorus (P). The atomic number of phosphorus is 15.

Thus, the atomic number of the element in the VA group, coming after nitrogen, is 15.

Answer 2

Nitrogen is the first element in group VA (group 15) of the modern periodic table and has an atomic number of 7. Elements in a group share the same number of valence electrons, which gives them similar chemical properties.
As we move down the group, the atomic number increases. The element that comes immediately after nitrogen in group VA is phosphorus. Phosphorus has an atomic number of 15. This means it has 15 protons in its nucleus and is located directly below nitrogen in the periodic table.
Therefore, the atomic number of the element of group VA that comes after nitrogen is 15.
