Question

vlociety of electron will be maximum in which orbit​

Answer 1

r=n^2 × alpha

Use this formula and v=2πr/T

Answer 2

Answer:

velocity of electron is maximum in first orbit.

Explanation:

this is because the kinetic energy of electron is the highest in first orbit.

which makes them to have highest velocity.

K.E = - 13.6 (Z)^2/ (n)^2

where Z is atomic no.

          n is orbit no.

so from the formula we can say that the energy decreases as we move towards the upper orbits.

and hence velocity decreases successively as we increase the orbit no.
