Problem

Aluminum reacts with a certain nonmetallic element X to form a compound with the general formula, AlX. Element X is a diatomic gas at room temperature.

Element X must be __________.

A. oxygen
B. bromine
C. sulfur
D. nitrogen
E. phosphorus

Solution

We are being asked what is the identity of element X that forms a compound AlX. 

Elements gain and lose electrons so that they have the same number of electrons as the noble gases.

Metals → lose electrons and gain positive (+) charge to become more like their closest noble gas
