Question

For a hydrogen-like atom described by the Bohr model, which relations are correct?

G1 Physics · Accepted Answer

For a hydrogen-like ion, the Bohr model gives rₙ = a₀n² ÷ Z, so A is correct. vₙ is proportional to Z ÷ n, so B is correct. Energy magnitude is |Eₙ| = 13.6Z² ÷ n² eV, so C is correct. Orbital period is proportional to orbit size divided by speed: Tₙ ∝ rₙ ÷ vₙ ∝ (n² ÷ Z) ÷ (Z ÷ n) = n³ ÷ Z². So D is also correct. Correct answers: A, B, C and D.
