Unveiling The Valency Of Phosphorus: Determining The Number Of Valence Electrons
Phosphorus, a Group 15 element, has 5 valence electrons. Valence electrons are the electrons in the outermost shell of an atom, determining its chemical behavior. Phosphorus’s electron configuration, 1s22s22p63s23p3, reveals its 5 valence electrons in the 3p orbital. Group 15 elements typically have 5 valence electrons, making phosphorus highly reactive as it seeks to complete…
