Which one of the following indicates correct order of atomic size of the given elements?

Options

  1. ALi > B > F >N
  2. BN > F > Li > B
  3. CF > N > B > Li
  4. DLi > B > N > F

Correct answer

D. Li > B > N > F

Step-by-step solution

The atomic size/radius decreases in a period from left to right. Thus, ₃ Li > ₅ ~B > ₇ ~N > ₉ ~F
