Q16 / 58 · KVPY 2016 (SA) · Chemistry

Among the element $\mathrm{Li}, \mathrm{N}, \mathrm{C}$ and $\mathrm{Be}$, one with the largest atomic radius is

  • Correct answer
    A
    $\mathrm{Li}$
  • B
    $\mathrm{N}$
  • C
    $\mathrm{C}$
  • D
    $\mathrm{Be}$

Solution

as we move left to right in a period atomic radius decrease due to increase in $z_{\text {eff }}$ so. greatest radius is of lithium.

Hence, the correct answer is option: 'A'.
