In the hydrogen atom, what is the total energy of an electron that is in an orbit that has a radius of 8.784 × 10^(-10) m?

The total energy of an electron in H atom is .

Explanation:

Given that,

Radius

We need to calculate the orbit number

Using formula of radius

Where, a₀ = boar radius

n = orbit number

Put the value into the formula

We need to calculate the total energy of an electron in H atom

Using formula of energy

Put the value into the formula

Hence, The total energy of an electron in H atom is .
