Question

if r is the radius of the first orbit the radius of n^th orbit of H-atom is given by

Answer 1

R is radius of first orbit therefore for nth orbit r(n) = n^2*R that is n squre multiply by radius of first orbit

Answer 2

Hey dear,

● Answer -
Radius of nth orbit in H-atom = Rn^2

● Explanation -
Let R be the Bohr radius.

For an element of atomic number Z, radius of nth Bohr orbit is given by -
Rn = R × n^2 / Z

For Hydrogen, Z = 1,
Rn = Rn^2
