Which of the following is the correct lewis structure for ammonia (nh3)? note: hydrogen and nitrogen have one and five valence electrons respectively.

Answer : Ammonia has molecular formula as

It has a central atom as Nitrogen bonded with 3 molecules of hydrogen around it, Nitrogen has atomic number 7

The electronic configuration of N is

The number of valence electrons are 5 in the outermost shell of nitrogen.

According to the octet rule, it needs 3 electrons to be an octet.

So, the valency of N is 3. And, Hydrogen has the valency as 1.

Therefore, three hydrogen are needed to be a stable compound of .

The lewis structure of is attached in the answer.

In the attached figure, the electrons of N are shown in dot and the electrons of H are shown in x.

i believe the answer is true.
