3
?
- A4
- B3
- C2
- D1
Solution & Step-by-step Explanation
In Aluminum Chloride (AlCl
3
), Aluminum (Al) belongs to group 13 and has a valency of 3, while Chlorine (Cl) is a halogen belonging to group 17 with 7 valence electrons. To complete its octet, each chlorine atom needs or shares 1 electron. Therefore, the combining capacity or valency of a chloride ion in this compound is 1.
