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
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 __________.
