Question

Velocity of electron in second orbit of He+ ion is

Answer 1

Explanation:

there is the formula for finding the velocity of any orbit of the particle who have 1 election ...

V(n) here n mean the number of orbit

c mean the velocity of light

z mean atomic number

n mean number of orbit

Answer 2

The answer to the above question is $(2.118)(10^8)em.s^{-1$.

Given:

He+ ion.

To Find:

The velocity of the electron in the second orbit of the He+ ion.

Solution:

Let the Velocity of the electron in the second orbit of the He+ ion be V.

Therefore,

$V=(e/137)(z/n) em.s^{-1}\\V=((2.998)(10^{10})/137)(2/2)em.s^{-1}\\V=(2.118)(10^8)em.s^{-1$

Hence, The velocity of the electron in the second orbit of the He+ ion is $(2.118)(10^8)em.s^{-1$.
