Mathematical Guess – Understood Coordinate System?

I was wondering. What coordinate system could exist for objects like the atom?

I don’t know but I guess that it might be that a distance measurement is to imprecise.

If we say the electron is positioned around the atom. This might sound vague. But I wonder if there then exist a number of things that are then understood.

It could mean that its understood that the electron should be available for action. Then this might make the position more precise.

So you have a coordinate system that enables quick functionality. The position should be so that all the functions of the atom are quickly achieved.

It is all these criteria that then I guess determines the position of the electron.
