Question
What is the reason “No hydrogen in Earth’s atmosphere” ?
✓

Answer

As the root mean square speed of hydrogen is much less than that of nitrogen, it easily escapes from the earth’s atmosphere. In fact, the presence of nonreactive nitrogen instead of highly combustible hydrogen deters many disastrous consequences.
