Question

the radius of the second orbut in hydrogen atom is​

Answer 1

The radius of the second Bohr orbit for hydrogen atom is (Planck's Const. h=6.6262×10-34 Js, mass of electron = 9.1091×10-31 kg , charge of electron e=1.60210×10-19C, permittivity of vacuum ∈0=8.854185×10-12kg-1m-3A2)

Answer 2

Explanation:

The radius of the second Bohr orbit for hydrogen atom is (Planck's Const. h=6.6262×10-34 Js, mass of electron = 9.1091×10-31 kg , charge of electron e=1.60210×10-19C, permittivity of vacuum ∈0=8.854185×10-12kg-1m-3A2)

When the hydrogen is in a second excited state, the value of n is equal to 3. Therefore, the radius of a hydrogen atom when it is in its second excited state is nine times its radius when it is in its ground state.
