For hydrogen atom, radius of first Bohr orbit would be

For hydrogen atom, radius of first Bohr's orbit is a for Li^(2+) the radius of first Bohr's orbit is

In Bohr.s model of hydrogen atom, radius of the first orbit of an electron is r_(0) . Then, radius of the third orbit is:

Calculate the radius of the third orbit of a hydrogen atom the radius of the first Bohr of hydrogen atom is 0.53 Å

The radius of the first Bohr orbit of hydrogen is a_0 . The radius of the third orbit would be :

In Bohr's model of hydrogen atom, the radius of the first electron orbit is 0.53 A. What will be the radius of the third orbit?
