If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
The second energy level contains eight valance electrons when it's full.
An atom with five electrons in the n = 3 energy level is typically phosphorus (P), which has the electron configuration of 1s² 2s² 2p⁶ 3s² 3p³. In this configuration, the 3s subshell contains 2 electrons, and the 3p subshell contains 3 electrons, totaling five electrons in the third energy level.
The energy possessed by electrons is typically in the form of kinetic energy, which is associated with their movement around the nucleus of an atom. Electrons can also possess potential energy, related to their position in an atomic orbital.
For an atom with 9 electrons, such as fluorine, the electron configuration would be 1s² 2s² 2p⁵. This means that the first energy level (1s) contains 2 electrons, and the second energy level contains 2 electrons in the 2s subshell and 5 electrons in the 2p subshell. The arrangement reflects the Aufbau principle, where electrons fill the lowest energy orbitals first before moving to higher ones.
The lowest energy level that has F orbitals is the fourth energy level. The Atomic orbital of any atom only contains 2 electrons.
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
Phosphorus has 5 electrons in its outermost principal energy level.
The second energy level contains eight valance electrons when it's full.
The innermost energy level always contains two electrons and the rest are arranged in 8s. for example the energy levels of calcium- 2,8,8,2. calcium contains 20 electrons. once the energy levels are filled upto 8 electrons then we move from onto the next energy level. hope this makes sense lol :)

It contains electrons, neutrons, protons, and energy.
It contains kinetic energy mainly. Potential energy is relative to its position
Electrons generally want to be in the lowest energy position, which is the ground state energy level. When electrons are in higher energy levels, they tend to transition back to lower energy levels to achieve stability by releasing energy in the form of photons.

The valance energy level contains 4 electrons in carbon.
Noble gases (except for helium which has 2 valence electrons).
