Question

Why we write electrons in orbital and not in orbit?

Answer 1

ORBIT

it is definite circular path of an electron around the nucleus

An orbit indicates an exact position of electron in an atom

ORBITAL

It is the region around the nucleus within which the probability of finding an electron is maximum

It does not specify an exact position of an electron.

Answer 2

An orbit is the circular path around the nucleus. It contains orbitals and vacant spaces. An orbital is a place where we can find electrons.
