What particle circles the nucleus of an atom?

Answer 1

Electron shells

At the same time i should point out that the bohr model isn't exactly accurate (i.e. electrons don't circule around the nucleus like planets around the sun). Electrons aren't at any one place at any particular time, they can only be described by what region they will most likely be in at a particular time. So in a way, this "empty space" is a region where there might be electrons (though very unlikely -> especially far away).

Answer 2

It is conventional wisdom to say that electrons orbit the nucleus. This is a misnomer. In reality, electrons move around the nucleus in unpredictable patterns that would not be described as orbits. The exact position of an electron cannot be known at any given time.

Answer 3

The nucleic envelope.

Answer 4

Electrons circle the nucleus of an atom.
