If the radius of first orbit of H-atom is x Angstrom, then the radius of the second orbit of Li^2+ i — Atomic Structure Chemistry Question
Question
If the radius of first orbit of H-atom is x Angstrom, then the radius of the second orbit of Li^2+ ion will be
Answer: B
💡 Solution & Explanation
r ∝ n^2/Z. For H(n=1, Z=1): r=x. For Li2+(n=2, Z=3): r = x*(4/3) = 4x/3.
