Question

Which family of elements does not combine with other elements unless under special conditions in a laboratory?

E. Noble Gases

B. Halogens

C. Metalloids

A. Alkali earth metals

D. Actinides

Answer 1

Answer:

Noble gases

Explanation:

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