NGSS.HS-PS1-1

The atom with the largest atomic radius in Group 18 is - 

• Ar
• He
• Kr
• Rn

NGSS.HS-PS1-1

As you move down a group, atomic radius increases because - 

• you add more and more neutrons
• you add more and more protons
• you add more and more shells (energy levels)
• you add more atomic mass

The atom with the largest atomic radius in Period 4 (row 4) is - 

• K
• Kr
• Fe
• Fe

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
