The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
The electron configuration of phosphorus is [Ne]3s2.3p3.

Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
Just one valence electron. The electron configuration for K-42 is 2-8-8-1, meaning that there is one electron in the outermost "shell" of the atom.
Each phosphorus atom requires three electros to fill its outer valence shell, giving the resulting ion the same electronic configuration as an atom of the next heavier noble gas, argon.
There are five valence electrons in phosphorus, hence there are five dots around P atom, one electron pair and three lone electrons.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.

With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
Nitrogen, Phosphorus, Arsenic, Antimony, and Bismuth all have 5 valence electrons
calcium has the complete electronic configuration: 2, 8, 8 2 and hence has 2 valence electrons.
It can reveal the number of valence electrons in the last shell.
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
Just one valence electron. The electron configuration for K-42 is 2-8-8-1, meaning that there is one electron in the outermost "shell" of the atom.
