Question

Calculate the energy value of the electron in the second orbit of hydrogen atom what will be tha radius of this this orbit?

Answer 1

Ok according to this question

There is a formula in chemistry regarding the Bohr's radius of hydrogen atom

r = r°n×n÷z

In this formula R is the radius and n is the radius in which the electron is lying

Z is the atomic number of the atom in the case of hydrogen atom Z is equal to one

r°=0.529

Therefore for Bohr's radius of second Orbit n is equal to 2

r= 0.529 × 2×2

r=2.116

Remember this value comes in A°

Therefore radius of second orbit is 2.116

I hope this will be helpful to you
