Q

Name and describe the group 1 elements.

A

The group 1 metals are called the alkali metals. They are stored under oil because they are so reactive. They react violently with water releasing hydrogen gas. Each alkali metal has one outer electron in its outer energy level.

Q

Name and describe the group 0 elements.

A

The group 0 elements are called the noble gases. They are very unreactive non-metals. Each noble gas has 8 electrons in the outer energy level. it used to be called group 8 but is often called 0 due to the lack of reactivity of the elements gives the a valency of zero.
