Question

How many valence electrons do the halogens possess? group of answer choices

Answer 1

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.
