Which of the following groups/families contain at least

one element that is gaseous at room temperature?

• alkali metals and alkaline earth metals

• alkali metals and transition metals

• noble gases and transition metals

• noble gases and halogens

When this element was discovered, it exhibited luster

and malleability, and it reacts vigorously with water. This

element is never found as a free element in nature and

always exists in a compound. To which group does this

element most likely belong?

• alkali metals

• halogens

• noble gases

• transition metals

Atoms of the noble gases are generally not reactive

because-

• they are neutral atoms

• they are charged

• their outer electron (valence) level is filled

• they are too large to react
