JEE Main 2025 Chemistry question
Radius of the first excited state of Helium ion is given as : a0 → radius of first stationary state of hydrogen atom.
Answer: (4)
Solution
r = a0(n²/Z) = a0(4/2) = 2a0 for He+ first excited state (n=2, Z=2).
Radius of the first excited state of Helium ion is given as : a0 → radius of first stationary state of hydrogen atom.
r = a0(n²/Z) = a0(4/2) = 2a0 for He+ first excited state (n=2, Z=2).
