Answer:valence electron of phosphorus is 5 Ask your question. Why are valence electrons responsible for the behavior of the atom. One of these was in phosphorus matches that were first sold in Stockton-on-Tees in the UK in 1827. There are two ways to find out. Valence Electrons. How do valence electrons determine chemical properties? The electron configuration can be visualized as the core electrons, equivalent to the noble gas of the preceding period, and the valence electrons: each element in a period differs only by the last few subshells. Phosphorus pentachloride (PCl 5) and sulfur hexafluoride (SF 6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom. These are contained in the third energy level of the atom. The Phosphorus Element … there are #15# electrons in total, there must be #5# electrons at the third energy level. around the world. Therefore, Its valence electrons should be 5. How many valence electrons are in carbon? Phosphorus has 5 valence electrons 2 from the 3s and 3 from the 3p. Since filled d or f subshells are seldom disturbed in a chemical reaction, we can define valence electrons as follows: The electrons on an atom that are not present in the previous rare gas, ignoring filled d or f subshells. For example, the electronic configuration of phosphorus (P) is 1s 2 2s 2 2p 6 3s 2 3p 3 so that there are 5 valence electrons (3s 2 3p 3), corresponding to a maximum valence for P of 5 as in the molecule PF 5; this configuration is normally abbreviated to [Ne] 3s 2 3p 3, where [Ne] signifies the core electrons whose configuration is identical to that of the noble gas neon. The electrons in the outermost shell are the valence electrons the electrons on an atom that can be gained or lost in a chemical reaction. Valence shell electrons (or, more simply, the valence electrons) are the electrons in the highest-numbered shell, or valence shell, while core electrons are the electrons in lower-numbered shells. Breathing in phosphorus vapour led to the industrial disease phossy jaw, which slowly ate away the jaw bone.
