Question

answer please this problem​

Answer 1

Answer:

Given,

Energy associated with Bohr's orbit in the hydrogen atom Eₙ=−13.6n2 eV

now, radius of Bohr's orbit, rₙ = 0.529 n2Z Å

or rₙ=r₁ n² [∵Z=1 for hydrogen ]

Given, rₙ=9r1

or r₁n²=r₁9

or n²=9

or n = 3

So, the energy associated with orbit of radius 9r1 can be given as :

E9=−13.69eV=−1.51 eV

or E9=−1.51 eV

Hope this helps you :)
