How is the Lewis dot diagram drawn for P4?


Quick Answer

The Lewis dot diagram for the P4 molecule is drawn by surrounding an upper case "P" with five dots. This represents the molecule’s nucleus and core electrons and is also referred to as a kernel. The dots illustrate the molecule’s electron pairs while excluding the five valence electrons found in the molecule’s outermost shell.

Moving clockwise from the top, the P4 molecule Lewis dot diagram consists of one dot placed directly above the P, another placed to the right of the P as though it were the period at the end of a sentence, another dot is below the P and the last two dots on the left of the P as though they were a colon preceding it.

P4 is one of the two most commonly found allotropes of the nonmetallic element phosphorus and is commonly known as white phosphorus. The element has an atomic number of 15 and contains five valance electrons in its outermost shell.
