The number of valence electrons for each member of halogen family is equal to six.

Text Solution

AI Generated Solution

To determine the number of valence electrons for each member of the halogen family, we will analyze the electronic configurations of the halogens: Fluorine (F), Chlorine (Cl), Bromine (Br), and Iodine (I). ### Step-by-Step Solution: 1. **Understanding Valence Electrons**: - Valence electrons are the electrons present in the outermost shell of an atom. These electrons are crucial for chemical bonding and reactivity. 2. **Identify the Halogen Family**: ...
