the answer is B) NH3

Answer: B) NH₃

Explanation:

The atomic number of nitrogen is 7.

Its configuration is: [He] 2s²2p³

Thus, it has 3 electrons in valence shell. Nitrogen is highly electro-negative.

The atomic number Hydrogen is 1. It has one valence electron.

Thus, when nitrogen bonds with hydrogen, the two share the electron to bond covalently. The correct formula would be B) NH₃
