The total number of electrons in Phosphorus (P) is 15 (its atomic number). The first energy level contains 2, the second energy level contains 8, and the third energy level contains 5.

The chloride ion (Cl-) has 8 electrons on the outermost energy level.

A neutral atom of magnesiumhas two electronsin its outermost energy level
This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
Phosphorus has five electrons in its outermost energy level (valence electrons).
Electrons in the outermost principal energy level are called valence electrons.
Transition elements can form bonds by losing electrons from both the outermost and next to the outermost principal energy levels.
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
11
The element is phosphorus and it contains 5 valence 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.
valence electrons are the electrons in the outermost energy level
Outermost have more energy than innermost. As electrons move inward, they release energy.
Electrons in the outermost energy shell of an atom are called valence electrons.
Halogens have six valence electrons in the outermost energy level.
