Question

A group of elements are highly inactive and are used by chemists because of their chemical stability.

Most are found in pure form. They never bond with other atoms because their outermost electron orbital
is full. In which element family are these elements found?

A) alkali metals

B) alkaline earth metals

C) halogens

D) noble gases

Answer 1

Those are the noble gases. I think they were called "noble" because
they behave like kings and other "noblemen" ... stuck up, and not
mixing with ordinary people.
