By going down the periodic table we are

• Adding electron shells (energy levels)
• Losing electrons
• Gaining more electronegativity
• Losing protons

What trend in atomic radius do you see as you go down a group/family on the periodic table? What causes this trend?

• Atom gets larger because electron shells increase
• Atom gets smaller because protons decrease
• Atom gets larger because protons increase
• Atom gets smaller because electron shells decrease

What trend in atomic radius do you see as you go across a period/row on the periodic table? What causes this trend?

• Atomic size decreases because more protons, more pull
• Atomic size increases because more neutrons, more pull
• Atomic size decreases because more protons, less pull
• Atomic size increases because more electrons, more pull
