Phosphorus has 5 electrons in its outermost principal energy level.


How many are electrons in phosphorus single?

The neutral atom of phosphorus has 15 electrons.


A neutral atom with an atomic number of 15 will have electrons in its outermost energy level?

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.

Explain how valence electrons in an atom are used to form a full outermost energy level?

Atoms form chemical bonds to achieve a full outermost energy level by sharing, gaining, or losing electrons. Valence electrons are the electrons in the outermost energy level of an atom, and having a full outermost energy level makes the atom more stable. This stability is achieved when there are eight electrons in the outermost energy level, known as the octet rule.
