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.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

answerca air mass;
