The dominant factor in determining the IE of the elements on moving down the groups is its

Options

  1. Aatomic radius
  2. Beffective nuclear charge
  3. CBoth (a) and (b)
  4. DNone of the above

Correct answer

A. atomic radius

Step-by-step solution

Along a group Z (effective nuclear charge) is almost constant. Thus, IE depends mainly on r_n (atomic radius).
