Answer:
An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.
Explanation:
According to Heisenberg's theory we cannot observe the position and velocity of an electron in an orbit, but if they were around the nucleus (in orbit), it would be possible to know its velocity and position, which would be contrary to the principle of Heisenberg So we can say that no electron revolves around a certain orbit around the nucleus, so we can only predict if the electron will be in the right position at the right time.
From there we find two definitions for electron orbital let's see:
