JEE Advanced 2024 — Paper 2 — Question 25

According to Bohr's model, the highest kinetic energy is associated with the electron in the

  1. Option A:

    first orbit of H atom

  2. Option B:

    first orbit of He+\mathrm{He}^{+}

    Correct
  3. Option C:

    second orbit of He+\mathrm{He}^{+}

  4. Option D:

    second orbit of Li2+\mathrm{Li}^{2+}

Answer: B

Step-by-step solution

K.E. =+13.6z2n2eV=+13.6 \frac{z^{2}}{n^{2}} e V

(A) n=1z=1\mathrm{n}=1 \mathrm{z}=1

K. E. =+13.6eV=+13.6 \mathrm{eV}

(B) n=1z=2\mathrm{n}=1 \mathrm{z}=2

K. E. =+54.4eV=+54.4 \mathrm{eV}

(C) n=2z=2\mathrm{n}=2 \mathrm{z}=2

K. E. =+13.6eV=+13.6 \mathrm{eV}

(D) n=2z=3\mathrm{n}=2 \mathrm{z}=3

K. E. =+30.6eV=+30.6 \mathrm{eV}
