Calculate the radius of first orbit of He ⁺ .

Options

  1. A26.45 pm
  2. B13.23 pm
  3. C48.62 pm
  4. D39.46 pm

Correct answer

A. 26.45 pm

Step-by-step solution

r _ n = 52.9( n )^2 Z pm He ⁺ is a hydrogen-like species having Z =2 . Radius of the first orbit of He ⁺= r ₁= 52.9 (1)^2 2 pm =26.45 pm
