What is nitrogen in periodic table?
Nitrogen (N), the seventh element of the periodic table, is a colorless, tasteless, odorless gas. It is found in living tissues, amino acids, Ammonia, and Nitric Acid. Nitrogen; N2; is a colorless, tasteless, odorless, and nontoxic gas. It is made by passing air over heated copper or iron.
What is the valency of nitrogen?
three
Valency of nitrogen is three as nitrogen has 5 electrons in its valence shell. It can therefore, accept three electrons to complete its octet.
