Electrons flow around the nucleus
In this model, the electrons move or orbit around the protons that are at the center of the atom. Electrons move around the nucleus, which contains the proton, in orbits that have a definite size and energy.
The scientist who discovered that atoms have an energy level is Niels Bohr in 1913. According to his model electrons move around the nucleus much the same as the planets rotate around the sun.
Electrons move around the atomic nucleus.
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.

Niels Bohr started the theory of electrons moving in exact orbits around the nucleus, but I've never heard of these orbits called 'tracks'

He proposed a new model of the atom in which there is a small dense positively charged nucleus with negatively charged electrons around the outside. The electrons are far away in comparison to the size of nucleus, so the majority of the atom is made up of empty space.
Rutherford's atom compared to the model proposed by his student Neils Bohr is very similar. Rutherford proposed a small positively charged nucleus with electrons orbiting around it. Bohr improved on this model by adding quantized energy levels to the orbits of electrons around positively charged nucleus.

They are not in the nucleaus, they orbit around the nucleus.
Electrons. They have a negative charge.
