At the top of the noble gases<span> is little helium (He), with a shell </span>that<span> is full with only two electrons. The fact </span>that<span> their outer shells are full means they are </span>quite<span> happy and don't need to react with other elements. In fact, they rarely combine with other elements. </span>That non-reactivity<span> is why they are called </span>inert<span>.</span>
