Question

How many valence electrons does Phosphorous have?

Answer 1

Valence electrons of Phosphorous

• Phosphorous is one of the very reactive elements
• Valence electrons are defined as the electrons present in the outermost electron shell of any element.
• They help in the formation of chemical bonds with other elements.
• Electronic configuration of Phosphorous is$1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^3$.
• There are $5$ unpaired electrons in the outermost shell of phosphorous.

Therefore, the number of valence electrons in phosphorous is $5$
