Answer 2

Answer:

Hello

Explanation:

First of all please correct your question. You should have written that - Why

nitrogen is 78% in the atmosphere? You know, it makes us easier to answer you people only if the question is correct. So, here's your answer:

The air around us is made of several different gases. Mostly nitrogen (78%) and some oxygen (21%) and traces other gases like argon, water, carbon dioxide, ozone, and more. ... The nitrogen molecule is heavier than most other molecules in the atmosphere, so it tends to settle towards the bottom.
