What is the valence electron configuration for phosphorus?
Electrons are locked up in covalent bond with valence electrons of four neighboring Si atoms. However, the 5th valence electron of phosphorus atom does not find a binding electron and thus remains free to float. When a voltage is applied across the silicon-phosphorus mixture, free electrons migrate toward the positive voltage end. Phosphorus, however, has empty 3d atomic orbitals that can be used to expand the valence shell to hold 10 or more electrons. Thus, phosphorus can react with fluorine to form both PF 3 and PF 5. Phosphorus can even form the PF 6 - ion, in which there are 12 valence electrons on the central atom, as shown in the figure below. In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.
The valence electron configuration for phosphorus is
Phosphorus Electrons How Many
Phosphorus has an electron configuration of
Phosphorus is found in group 15, the other non-metals on the periodic table.
Phosphorus is in the 3rd energy level, (3rd row) and 3rd column of the 'p' block
The valence electrons are always found in the 's' and 'p' orbitals of the highest energy level of the electron configuration making the valence orbitals 3s and 3p and making the valence configuration
I hope this was helpful.
