Some electrons are close to their atomic nucleus,
others are farther away.
Which ones have more potential energy?
Homework Answers
Answer: the electrons , those are farther away from nucleus have more potential energy than those electrons which are nearer to the nucleus.
Detailed explanation is given below
explanation: The electrons which are farther away from nucleus are weakly held by nucleus and they can be removed easily by the minimum loss of energy. Therefore they have much higher energy in compare of those electrons which are tightly held by nucleus I.e. nearer electrons to nucleus.
Also,
The coloumbic interaction energy is numerically equal to = -Ze^2/4π€r
But e = charge on electron, €= permittivity ,r= distance between electron and nucleus etc..
Thus electron which are far away have smaller 1/r and so this energy term is less negative ( and thus larger)

Which of these statements is true? The number of electrons outside the nucleus is the same as the number of neutrons in the nucleus. The mass number of an atom is the number of protons plus the number of neutrons. The atomic number of an atom is the number of valence electrons outside the nucleus. In an ion, the number of electrons must be equal to the number of protons.

Suppose some nucleus undergoes decay, releasing 5.4 MeV of
energy. If the daughter product of this reaction is 93X237 (atomic
mass = 237.04816) , it will recoil away as the particle leaves.
Determine (a) the energy of the daughter product and (b) the energy
of the particle (atomic mass = 4.002603 u). Assume that the energy
of each particle is kinetic energy, and ignore any other small
amounts of energy that might be carried away by other emissions. In
addition,...

When a proton encounters a large atomic nucleus, to a good approximation, we can assume that the large nucleus is fixed in space. The main force between the nucleus and the proton is electrostatic. Assume a nucleus of charge 29 e is fixed at the origin, and a proton approaches it moving along the x-axis. When the proton moves directly at the nucleus, it turns a a distance 621 nm from the center of the nucleus, called its turning radius....

When a proton encounters a large atomic nucleus, to a good approximation, we can assume that the large nucleus is fixed in space. The main force between the nucleus and the proton is electrostatic. Assume a nucleus of charge 25 e is fixed at the origin, and a proton approaches it moving along the x-axis. When the proton moves directly at the nucleus, it turns a a distance 789 nm from the center of the nucleus, called its turning radius....

a) Suppose 7.0 × 10-19 J of work is done to move the nucleus of an atom from some very far away position to a location near a fixed positive charge. What would the electric potential energy of the nucleus be? b) If the nucleus is now released, how much kinetic energy will it have when it returns to a very far away position?
