Periodic Trends Review Game

Atomic Radius is...

• the relative size of the atom's nucleus
• the relative size of the atom's electron cloud
• the energy required to shield the outer electrons from the nucleus
• a measure of the ability of an atom to attract electrons

As you move down the periodic table atoms get bigger.  This is because ____________.

• The atoms have more mass.
• The atoms have more protons.
• The atoms have more energy levels
• The atoms have more nuetrons

Francium (Fr) has the lowest ionization energy in Group 1 because - 

• it has the smallest number of valence electrons
• it has the greatest atomic mass
• it has the greatest number of protons, so it attracts its electrons the strongest
• its 1 valence electron is very far from the nucleus, so little energy is needed to remove it
