Electron shell further away from nucleus higher Energy lvl?

Using electrical potential energy =1/4πεo Q1Q2/r , a particle further away from nucleus has lower magnitude of energy

Using coulomb's law, a particle further away from nucleus experiences weaker attraction, hence less energy is needed to maintain orbit* around that e-shell compared to a electron shell closerr to nucleus, hence the one closer to nucleus supposedly should have higher energy.

*i know in reality e- does not orbit around a atom, but its position exists as a probability density of radial probability function.

No energy is needed to "maintain an orbit" regardless of what the energy level is. What requires energy is removing an electron from a bound state.

[SORRY TYPO] :
It's position exists as a probability density OR* radial probability function

Ahh yes ! Okay, i understand better now.
Yes, no energy is needed for an electron to maintain an orbit as acceleration is perpendicular to direction of motion

Removing e- from a atom or transitioning it to a higher energy level requires energy.

Thank you , orodruin !
