Question

6. Helium is a noble gas because it is very reactive. true or false
​

Answer 1

Answer:

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

Answer 2

Answer:

True ..

Explanation:

Chemical Properties of Noble Gases

That's because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons. ... Therefore, noble gases are rarely involved in chemical reactions and almost never form compounds with other elements.
