In order to draw the lewis structure of PF3, first of all you have to find the total number of valence electrons present in the PF3 molecule. (Valence electrons are the number of electrons present in the outermost shell of an atom).
A phosphor is a substance that exhibits the phenomenon of luminescence; it emits light when exposed to some type of radiant energy. The term is used both for fluorescent or phosphorescent substances which glow on exposure to ultraviolet or visible light, and cathodoluminescent substances which glow when struck by an electron beam (cathode rays) in a cathode-ray tube.

WebThe atomic mass of phosphorus is 30.973762 u. Atomic mass is defined as the number of protons and neutrons in an atom where the mass of each proton and neutron is approximately 1 amu (1.0073 and 1.0087, respectively). The electrons within the atom are so tiny compared to the protons and neutrons that their mass is negligible.
WebMar 21, 2024 · A neutral phosphorus atom has 15 electrons. Two electrons can go into the 1s subshell, 2 can go into the 2s subshell, and 6 can go into the 2p subshell. That leaves 5 electrons. Of those 5 electrons, 2 can go into the 3s subshell, and the remaining 3 electrons can go into the 3p subshell. Thus, the electron configuration of neutral phosphorus ...
