Question

Which option describes a common property of the elements, nitrogen (N), phosphorus (P), arsenic (As)?
Hint: Review your periodic table.

They have the same amount of reactivity.
They have the same amount of atomic mass.
They have the same number of valence electrons.
They have the same atomic radius size.

Answer 1

The common property of N, P, and As is that they have the same number of valence electrons.

Atoms of nitrogen have the least atomic mass and are smaller and more reactive than those of phosphorus and arsenic.

Answer 2

The elements, nitrogen (N), phosphorus (P) and arsenic (As) have same number of valence electron. So, option third describe the common property of elements , nitrogen (N), phosphorus (P) and arsenic (As).

What is periodic table?

The table in which elements can arrange according to their common physical and chemical properties.

In this question,

The nitrogen (N) is more reactive than phosphorus (P) and arsenic (As).

The nitrogen (N) is less atomic mass than phosphorus (P) and arsenic (As) .

The nitrogen (N) is less atomic radius size than phosphorus (P) and arsenic (As) .
