I know this is a gaming forum and everything but I've come here to ask you guys a question that my bro is having problems with (I dont really care for this stuff, so I dont really know the answer), and I'm just wondering if any of you smart ones could please solve it. I understand I shouldn't come here to ask you guys anything really, as its my bro's responsibility, but its appreciated if you can, and please explain how you found the answer (or provide a link). Thanks.
Element Q is a metal with two valence electrons, and element X is a non-metal with five valence electrons. They combine to form an ionic compound. What is its forumla?
