The correct option is C.i.e. AlCl3
Given:
The valence of aluminum is +3, and the valence of chlorine is –1. Thus, 3 chlorine atoms each of (-1 charge )combine to make the charge balance because of Al (3+). Thus, 1 atom of Aluminum (Al) binds with three atoms of Chlorine (Cl).Thus, the net foromula becomes AlCl3
AICI3
