The potential energy of an electron orbitting in an atom can be approximated by the coulomb potential
V(r) = - e2/(4*pi*epsilon0 *r)
Where r is the distance of the lectron from the nucleus. This approximation is for atoms with just 1 electron and 1 proton (i.e Hydrogen) For other atoms it is a bit more complicated but this can still be used as a rough approximation.
This is from the bohr model of the atom I think

What is ionization potentials?
Ionization potential is the energy required to remove one electron from an atom in the gaseous state. The units may be eV(electron volts) or kJ/mol. These are readily interconverted. Usually the ionization potentials for successive electrons are quoted as the first ionization potential, second ionization potential etc.
How is a hydrogen atom is different than a proton?
A hydrogen atom, H, is a proton (as nucleus) with one electron orbitting around it. A proton is just (the same as above) one proton, which lacks the electron: H+ .
What happens to the energy that an electron has as its distance from the nucleus of the atom increases?
Physically put, the electron has more energy the farther ( higher ) it is from the nucleus. Simple potential energy. PE = mgh
What is step potential in quantum mechanics?
The potential step is the barrier for particles to enter in to some region ,for example ,consider an electron with incident energy greater than the potential energy of an atoms ,will easily penetrate in to the atom an will comes out with some net changes in its energy and wave function , On other hand the electron having smaller energy than the potential of atom can not penetrates in to the atom ,it will bounces back from the atom , so here the neutral atom behaves as a potential step (barrier) BY SAMI UL HAQ IIUI , DEPARTMENT OF PHYSICS (NANO TECHNOLOGY ) MOB 00923038400484 SAMI786NANOTECH@GMAIL.COM
Is total energy of revolving electron in an atom zero?
actually total energy is the sum of potential energy and kinetic energy....potential energy= -2*kinetic energy . By using this relation you will get that sum of potential and kinetic energy is equal to the magnitude of kinetic energy and it is less than zero...hope this will be enough for you....
What is more- potential energy or kinetic energy of an electron in hydrogen atom?
Both are equal.
An electron loses potential energy when it?
shifts to a more electronegative atom.
What is the exact meaning of ionization potential?
The energy required to remove completely an electron from its atom.
What is ionization potentials?
Ionization potential is the energy required to remove one electron from an atom in the gaseous state. The units may be eV(electron volts) or kJ/mol. These are readily interconverted. Usually the ionization potentials for successive electrons are quoted as the first ionization potential, second ionization potential etc.
How is a hydrogen atom is different than a proton?
A hydrogen atom, H, is a proton (as nucleus) with one electron orbitting around it. A proton is just (the same as above) one proton, which lacks the electron: H+ .
The energy required to remove an electron from a neutral atom is the atom's?
Ionization Energy or electron energy

Which electrons have the most energy in a atom?
Potential energy. Potential energy = mass * gravitational constant * height As you see, the further the electron is from the nucleus ( how " high " it is ) the more energy it contains. So, that would be the outer valance electron(s).
Electrons exist only at fixed levels of potential energy However if an atom absorbs sufficient energy a possible result is that?
An electron may move to an electron shell farther out from the nucleus.
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
What energy is required to remove an electron from an atom?
The energy needed to remove an electron from an atom (in the gaseous state) is called the IONIZATION ENERGY.
