Video Transcript

the data given is phosphorus, and the outcome expected is the number of balance Electrons associate ID with phosphorus. Now, if we look into the periodic table, we see that phosphorus represented by the symbol capital P contains 15 electrons. Now, these 15 electrons are filled into the energy levels or our vitals in the following manner. One is to the west to to be six, three years to on three p. Creep. Now Valence. Electrons are the electrons present in the outermost shell off the atom. Now, if we look into the configuration of phosphorus, we see that the outermost shell that is three s and three p corresponds to five electrons, so the number off balance electrons associate it with phosphorus are five.
