They want to get rid of their only valance electron

They only need one more electron

They are non reactive, they have a full shell

The total number of neutrons in the unknown element

The total number of particles in the nucleus of the unknown element

The number of valence electrons in the unknown element

It is most likely a liquid metal.

It is most likely a solid metal.

It is a metalloid.

It is a non-metal.

They balance out the charges from the protons.

They are used in bonding.

They keep the atom stable.

They are not important to the atom.
