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.
A phosphorus atom typically gains three electrons to achieve a stable electron configuration in an ionic bond. This allows it to attain a full outer valence shell with eight electrons, similar to the electron configuration of a noble gas.
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has an electron configuration of 2, 8, 5.
Magnesium (Mg) has atomic number 12, so the electron configuration is1s2 2s2 2p6 3s2. The VALENCE electron configuration would simply be 3s2.
To determine the number of valence electrons in an atom using its electron configuration, look at the highest energy level (n) in the electron configuration. The number of electrons in this energy level is the number of valence electrons.
To determine the number of valence electrons in an atom based on its electron configuration, look at the outermost energy level of the atom. The number of electrons in this energy level is the number of valence electrons.

Valence electrons are the outermost electrons in an atom that are involved in chemical bonding, while electron configuration refers to the arrangement of electrons in an atom's energy levels or shells.
The electron configuration for an atom with 15 electrons is 1s2 2s2 2p6 3s2 3p3. This corresponds to the electron arrangement of the element phosphorus (P).
The ground state electron configuration for phosphorus is 1s2 2s2 2p6 3s2 3p3. This means phosphorus has 15 electrons distributed in its electron shells according to the aufbau principle.
