Answer
Explanation:
Step1: Recall chlorine's electron - configuration
Chlorine (Cl) has atomic number 17. Its electron - configuration is 1s²2s²2p⁶3s²3p⁵.
Step2: Identify valence electrons
Valence electrons are in the outermost shell. For Cl, the outermost shell is the third shell (n = 3), and it has 2 + 5=7 electrons.
