95% of the time (or any other percentage you choose), the electron will be found within a fairly easily defined region of space quite close to the nucleus. Such a region of space is called an orbital. You can think of an orbital as being the region of space in which the electron lives.
The orbit around the nucleus within which the electron rotate is called shells or Energy levels. Each discrete distance orbit from the nucleus corresponds to a certain energy level. The electron which rotates in the lowest orbit has lowest energy level and in the outermost orbit, electrons have higher energy levels. Hence energy levels increase as the distance from the nucleus increases.
