Q4 / 160 · TS EAMCET 2022 (20 Jul Shift 2) · Chemistry

The successive ionisation energies (starting from the $1^{\text {st }}$ ) of anelementare $801,2430,3660,25,000$ and $32,800 \mathrm{~kJ} \mathrm{~mol}^{-1}$, respectively. The element is

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

Solution

There are five successive ionization energies means 5 electrons are successively removed. Therefore, the atomic no. of the element is 5 . $\therefore \quad$ The element is ' $\mathrm{B}$ '.

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