These are spherical Every energy level contains one S-Orbital An S-Orbital in the first energy level is a 1s orbital An S-Orbital in the second energy level is a 2s orbital etc.
At the higher levels the lobes get more elongated with the most likely place to find the electron more distant from the nucleus. The orbits are analogous to a set of stairs in which the gravitational potential energy is different for each step and in which a ball can be found on any step but never in between. Each energy level consists of a number of sub levels which are labelled as spd or f.
