Periodic Table Valence and Atoms

All atoms are most stable with (or would "prefer") how many electrons in their valence shell?

• 18

Valence electrons are: 

• Electrons farthest away from the nucleus
• Electrons closest to the nucleus
• Electrons that just come and go - they don't stay with the atom
• Electrons in the second shell
