In any atom, the electrons that have the most energy are the outermost, because the greater energy an electron has, the greater its velocity, and when anything has greater velocity, it has a greater momentum and a greater orbit.
Think of a planet orbiting the sun. If the planet were faster, it would start to have greater inertia and be affected by the sun's gravity less, causing the orbital radius to increase.
The case is similar with electrons. Since energy gives electrons a higher velocity, they start to orbit farther away from the nucleus. Therefore, the electrons in the outermost energy level or orbital always have the greatest energy and are less stable because of it.

What are the energy levels of an atom occupied by?
that depends on the number of electrons the more electrons the more energy
What happen when electron change energy level?
When electrons change energy levels they usually become more stable. Sometimes when electrons change energy levels they become unstable though.
Which components of an atom are arranged in various energy levels or orbitals?
electrons
How are electrons arranged in the atom?
Electrons are arranged around the atomic nucleus forming the electron clouds.
What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
What are the energy levels of an atom occupied by?
that depends on the number of electrons the more electrons the more energy
Which energy levels holds more than 8 electrons?
Energy levels from 3 and above can have more than 8 electrons maximum. Maximum of 2n2 electrons is possible where n is the energy level.
When an atom has one or more electrons in higher energy levels?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
What do electrons that occupy high energy levels have more of?
They have more speed.
Do neutrons have more energy than electrons?
No, Neutrons are nuetral so they do not move in different energy levels. Only Electrons do.
Are electrons located in energy levels or electron cloud?
Electrons are located in energy levels within the electron cloud.
What element has 3 valence electrons and 3 energy levels?
What has three energy levels and six valence electrons
What element has 3 energy levels and 3 valence electrons?
What has three energy levels and six valence electrons
What happen when an atom has more electrons that can fit in one energy level?
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.
Why does sodium have electrons that are not arranged in its energy levels?
Sodium atoms do have electrons that are arranged in energy levels. The electron configuration of sodium is 1s22s22p63s1.
What does t he energy levels of an atom hold?
The energy levels of an atom hold electrons.
How many valence electrons are on the first 3 energy levels?
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.
