Question

What has research determined about the orbit of an electron around a nucleus?
Electrons orbit and remain with in specific energy rings.
Electrons orbit the nucleus in circular motions exactly as shown on the classic Bohr model.
Each sub-level electron type has a unique path where it will likely be found.
Electrons orbit in exact energy levels.

Answer 1

I think the correct answer from the choices listed above is the second option. The research that determined about the orbit of an electron around a nucleus would be that electrons orbit the nucleus in circular motions exactly as shown on the classic Bohr model.

Answer 2

Answer: the third option, each sub-level electron type has a unique path where it will likely be found.

Explanations:

1) Bhor's model of electrons orbiting the nucleus of the atom was shown to be wrong.

2) The actual model of the atom is the quantum atom model.

3) The quantum atom model depicts the electron in regions called orbitals.

4) The orbitals are the sublevels of energy (or subshells).

These sublevels (orbitals) are identified with the letters s, p, d, and f.

The orbitals s are spherical, the orbitals p are like a dumbbells, d and f orbitals have weirder shapes.

Those orbitasl are kind of electron clouds. The orbitals are defined as regions of the space around the atomic nucleus where the electrons are likely located.
