Question

Number of electrons in the valence orbit of nitrogen in an ammonia molecule are

• A. 8
• B. 5
• C. 6
• D. 7

Answer 1

Answer: (A)

8

Answer 2

The electronic configuration of nitrogen is $\, \, \, \, \, \, \, \, \, \, _7 N=1s^2,2s^2 2p^3$ It has 5 electrons in valence shell, hence in ammonia molecule it completes its octet by sharing 3 electrons with three H-atoms, therefore it has 8 electrons in its valence shell in ammonia molecule
