A. 3

B. 6

C. 4

D. 2

E. 5

Answer 1

5

Answer 2

The number of valence electrons are equal to the main group number.
So for nitrogen it would be?

Answer 3

atleast for the P and S block.

Answer 4

Nitrogen is in Group 5A, so is 5 the answer?

Answer 5

yes

Answer 6

Exactly.

Answer 7

Another example: oxygen is in main group 6 therefor 6 valance electrons.

Answer 8

Thank you!!!

Answer 9

Atomic no for nitrogen is 7. That means 7 electrons. 2electrons on first orbit, 5 electrons left for the the valence orbit. Hence 5 valence electrons
