A neutral atom of calcium has five energy levels that are partially or fully occupied. These energy levels are filled with electrons according to the Aufbau principle, with the first two levels (K and L) being fully filled while the remaining three levels (M, N, and O) are partially filled.
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher energy levels.
A neutral atom of xenon has 6 energy levels, with 54 electrons occupying those levels. Xenon has 54 electrons in total, so no electrons would be left over in a neutral xenon atom.
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
In a phosphorus atom, the energy levels are filled with electrons according to the aufbau principle, which states that electrons fill the lowest energy levels first before moving to higher energy levels. Phosphorus has 15 electrons, which fill the 1s, 2s, 2p, 3s, and 3p orbitals in that order.
The neutral atom with the specified electron configuration has 10 electrons in total. This atom is neon (symbol: Ne), which has a total of 10 electrons and has its first two energy levels filled with 2 and 8 electrons, respectively, while the third energy level contains 6 electrons.
This atom is nitrogen with an atomic number of 7. The first two energy levels (K and L) are filled with 2 and 5 electrons, respectively. The third energy level (M) has 5 electrons, giving a total of 12 electrons for the neutral nitrogen atom.

Electrons located in the innermost energy levels (such as the 1s level) have the lowest energy. These energy levels are closest to the nucleus and are filled first in an atom according to the aufbau principle.
An element with 2 energy levels and 2 electrons in the outer layer is beryllium (Be). Beryllium has an atomic number of 4, with 2 electrons in the first energy level and 2 electrons in the second energy level, making it a neutral atom.
The element with 3 energy levels and 7 valence electrons in a neutral state is chlorine (Cl), which has an electron configuration of 2-8-7.
the element sodium has 1,000,000 million energy levels.
