Question

What should be the circumference of the second orbit of hydrogen atom?

Answer 1

In hydrogen atom, the circumference of the orbit of electron placed in the second orbit can be calculated using the Bohr’s theory of orbit electrons. It is estimated that as per this theory, the second orbit of the electron has its circumference equal to 600 nm.

As per this, the second orbit in hydrogen atom is having its circumference equal to approximately 2.116 A⁰ while the radius of the second orbit of the hydrogen atom can be calculated using the Plank’s constant h = 6.6262 X 10 -34 Js as compared to the mass that is equivalent to around 1.60210 X 10 -19 C.
