I'm not sure exactly how to answer your question because I'm not sure how much you know.

I will start with this and you can guide me from there about anything you are unsure of or if it doesn't actually answer your question:

The orbitals are spatial representations of a probability distribution for an electron with those particular quantum numbers. But the electron can be found virtually anywhere in space. For example, the electron in the 1s orbital has n = 1, l = 0 quantum numbers. This electron ends up spending most of its time in a spherical shell around the nucleus. But there is a calculable chance that the electron will be closer to the nucleus, farther from the nucleus (or in Cape Cod for that matter!) It is not by any means confined to that spherical shell.

I know that the electron will move ni the spherical space of 1s orbital.But wont it loose energy by going near the nucleus and away from th nucleus?
thank you.

No its the time energy uncertainty principle that allows it to be somewhere
you think it can't be:

$\frac{\Delta E}{ \Delta t} \ge \frac{\hbar}{2}$
