How many valence electrons do the halogens possess? group of answer choices
jok3333 [9.3K]

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

Sladkaya [172]

M1 = 17.45 M

M2 = 0.83 M

V2 = 250 ml

M1. V1= M2. V2

V1 = (M2. V2)/M1 = (0.83× 250)/ 17.45= 11.89 ml
