Hey dear,
● Answer -
Valence electrons => 3
Valency => +3
Compound name => Aluminum chloride
Compound formula => AlCl3
● Explanation -
Since element belongs to 3rd period and 13th group it must be Aluminum (Al).
Electronic configuration of element is roughly 2, 8, 3. Thus this element can lose 3 valence electrons and have valency +3.
Valency of X i.e. Al is 3 & that of Cl is 1. Thus compound formed is aluminum chloride (AlCl3).
Hope this helps you...
