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

Elements in the same column of the periodic table always have the same # of _______ as one another.

• Protons
• Neutrons
• Electrons
• Valence Electrons

How do electrons of an element determine that element's reactivity?

• If the valence shell has missing electrons it is very reactive to attract or lose more electrons.

• If the valence shell has a full ring of electrons it is very reactive because it needs more.

• If the valence shell has a full shell of electrons it is very reactive because it is already full.

• If the valence shell has missing electrons it is not reactive because it is missing electrons.
