D. have incomplete outer orbits ??????????????????PLEASE HELP??? The reactivity of an atom is determine by the vacancy (unfilled orbital) in the outermost shell of an atom. Greater vacancy implies greater reactivity (and vice versa). Link to comment Share on other sites More sharing options...
Sayonara Posted July 22, 2008 Share Posted July 22, 2008 As you'll have gathered from the above answers, the way to address questions like this is to turn them around. In this case, your question becomes "what is it about atoms that makes them reactive?" You might not already know why that is, but it makes it easier to research the answer!
