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.
Phosphorus has more outer electrons than silicon. Phosphorus has 5 outer electrons in the third energy level, while silicon has 4 outer electrons in the third energy level.
Phosphorus has 15 electrons. The electron distribution in a phosphorus atom is 2 electrons in the first energy level, 8 electrons in the second energy level, and 5 electrons in the third energy level.
Phosphorus has 5 electrons in its outermost principal energy level.
Chlorine has 7 electrons in its third 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.
Phosphorus has five valence electrons.
Phosphorus has more outer electrons than silicon. Phosphorus has 5 outer electrons in the third energy level, while silicon has 4 outer electrons in the third energy level.
Phosphorus has five electrons in the third energy level (n=3).

Phosphorus has 15 electrons. The electron distribution in a phosphorus atom is 2 electrons in the first energy level, 8 electrons in the second energy level, and 5 electrons in the third energy level.
Phosphorus has 5 electrons in its outermost principal energy level.
Phosphorus has 5 electrons in the the third shell.
the energy levels are as follows: first shell 2 second shell 8 third shell 5
The element with five electrons in the third energy level (n=3) is phosphorus (P). In its electron configuration, phosphorus has the atomic number 15, with the distribution of electrons as 1s² 2s² 2p⁶ 3s² 3p³. Thus, it has five electrons in the third energy level (2 in the 3s subshell and 3 in the 3p subshell).
A neutral atom with an atomic number of 15 (phosphorus) will have 5 electrons in its outermost energy level. This is because the atomic number tells us the number of protons, which is equal to the number of electrons in a neutral atom. The outermost energy level for phosphorus is the third energy level.
There are 8 electrons in the second energy level of an atom of phosphorus. This is determined by the electron configuration of phosphorus, which is 1s2 2s2 2p6 3s2 3p3. The second energy level includes the 2s and 2p orbitals, which together hold a total of 8 electrons.
Iron has 26 electrons. The third energy level can hold a maximum of 18 electrons. Therefore, there are 18 electrons on the third energy level of iron.
