Group 2, the alkaline earth metals

Explain why the atomic radius increases from magnesium to barium.

A
  • Each element has an extra electron shell.
  • Increased shielding cancels the increased nuclear charge.
B
  • Each element has an extra electron shell.
  • Increased nuclear charge outweighs the increased shielding.
C
  • Each element has one fewer electron shell.
  • Decreased shielding weakens the nuclear attraction.
D
  • Each element has the same number of electron shells.
  • Increased nuclear charge pulls the outer electrons closer.
