One evening last summer, as I strolled along the promenade in Limbe, a small, scenic port town in southwestern Cameroon, I was stopped by a well-dressed young man who greeted me warmly and took me by the hand.
Phosphorus has 3 shells. The outer shell contains 5 electrons. The electronic configuration is :- <br /> 1s2, 2s2, 2p6, 3s2, 3p3.
Phosphorus atoms have 15 electrons and 15 protons with 5 valence electrons in the outer shell. Characteristics and Properties. Phosphorus is a highly reactive element and, as a result, is never found on Earth as a free element.Elemental phosphorus comes in various allotropes (different crystal structures) including white, red, violet, and black phosphorus. The two major forms of phosphorus are white and red.hosphorus atoms have 15 electrons and 15 protons with 5 valence electrons in the outer shell. Characteristics and Properties.
