Answer 2

The gaseous element "nitrogen" forms the “largest proportion” of earth’s atmosphere.

This followed by oxygen. Nitrogen counters the property of oxygen to be a supporter of combustion. The atmosphere contains “seventy eight per cent of nitrogen”.

Nitrogen is a chemically inert gas, colourless, odourless and even tasteless with an atomic number of 7. It is diatomic in nature. It is lighter than air. It is easy to liquefy at a temperature below 66 K.
