This element is likely phosphorus (P), which has 15 electrons in total. With 5 electrons in the second energy level, phosphorus has 2 energy levels: the first energy level with 2 electrons and the second energy level with 5 electrons.
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.
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
the energy levels are as follows: first shell 2 second shell 8 third shell 5
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.

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.
Phosphorus atoms have five valence electrons. You can know this because P is in group 15/VA. The number of valence electrons is the same as the VA group number (5), or group number 15 minus 10, which is 5.
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.
There are 3 electrons in the 3rd principal energy level of a phosphorus atom. This is because the atomic number of phosphorus is 15, indicating that it has 15 electrons distributed in different energy levels, with 5 of those electrons occupying the 3rd energy level.
No, the tendency is to fill out lower energy levels first.
Neon has the 1s2, 2s2, and 2p6 levels filled.
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 :)
