How many valence electrons do the halogens possess? group of answer choices
1 answer:
The valence electron does the halogens possess are 7
Valence electrons are found in the outermost energy level of an atom They are involved in the formation of chemical bonding with other atoms. The halogens elements are found in group 17 on the periodic table The halogens include fluorine, chlorine, bromine, iodine and astatine. They have seven valence electrons, so they are extremely reactive as they only need one more to fill their outer shell. By octet rule we can say that the electron with 8 outer most shell is full and stable.
Hence the halogens posses 7 valence electron
