Electrons generally orbit in ellipses.
On Bohr's model of the atom, electrons move in circular orbits around the nucleus. These orbits have specific energy levels, and electrons can transition between these orbits by either absorbing or emitting energy in the form of photons. The orbits were quantized, meaning that only certain orbits were allowed for the electrons to move in.
The electrons circle the nucleus in specific orbits.

What happens to the energy of the electrons in the orbits of each orbit increases
The Bohr model fails to recognize the fact that electrons do not exist in predictable orbits about the atomic nucleus; additionally, they do not account for the 3-d geometrical shapes of electron orbitals.
The orbits of electrons described by Bohr are also known as electron shells or energy levels. These orbits are specific regions around the nucleus where electrons are most likely to be found.

Krypton has 8 valence electrons.
I suppose that you think to electrons.
The inner orbits (closer to the nucleus) hold fewer electrons than the outer orbits. Each orbit has a maximum capacity of electrons it can hold based on its energy level. The further away an orbit is from the nucleus, the higher its energy level and the more electrons it can hold.
