Rubidium reacts with a certain element to form a compound with the general formula Rb2X. What would the most likely formula be for the compound formed between aluminum and element X?
______Al2X
______Ak2X3
_______ Al2X2
_______ AlX2
Homework Answers
The Valency of Rb is 1 and it is forming Rb2X
It means that the Valency of X is 2.
So to Satisfy this Valency with Aluminium, the formula should be Al2X3.
