Which electrons has the most energy in an atom?
The energy level that holds a maximum of 8 electrons holds the most energy because 8 electrons = maximum stability so it takes more energy to break away an electron. The energy level that holds a maximum of 8 electrons holds the most energy because 8 electrons = maximum stability so it takes more energy to break away an electron.

What is ionization energy?
Briefly, it is the energy required to completely remove a valence (outer shell) electron from its atom when forming an ionic bond.See related links below for more info
It takes 208.4 kJ of energy to remove 1 mole of electrons from an atom on the surface of rubidium metal How much energy does it take to remove a single electron from an atom on the surface of solid r?
3.460e-19
What energy is needed to remove an electron from its outer most shell?
This is called the ionization energy and an is different for each electron in the atom. Electrons in the outer shell (furthest from the nucleus) have the lowest ionization energy, electrons in the innermost shell (closest to the nucleus) have the highest ionization energy.
Why does an electron occupy the 4s orbitals before the 3rd orbital?
Because the 4d electrons experience a lower effective charge from the nucleus at this point than the 5s electrons. Long story is that it has to do with the energy lost from spin-pairing. That means that it takes more energy to spin-pair the 5s electron than the energy difference between the 4d and 5s orbitals, so it will push the electron up to the 4d orbital since it requires slightly less energy. At the periods containing cromium and copper, this is where that effect takes place. You can demonstrate this to yourself by calculating the Z(eff) for the electrons using Slater's Rule, and you will see the change in Z(eff) for yourself.
Why does lithium have a smaller atomic radius then potassium?
because the second ionisation means removing the second electron from the potassium atom. Potassium only has one electrin in its outer most shell so the second electron would be in another electron shell which is closer to the nucleus meaning there is a stronger attraction to that electron because of the protons in the nucleus which are positive and attrct the negative electrons so more energy is needed to remove the second electron

Electrons that have been excited by light energy absorbed by a chlorophyll molecule?
Some of the electrons become excited. means that they have comparatively more energy. the flow of energy takes place through these excited electrons. these are transferred form the reaction center chlorophyll to the primary electron acceptors.
When electrons gain additional energy do they move farther away from the nucleus?
In general, electrons farther from the nucleus will have more energy than electrons closer in. These "outer" electrons are said to be in higher Fermi energy levels, and they have more kinetic energy than the electrons in lower orbitals. Consider that electrons give up energy to "fall into" closer orbitals, and they will, in general, have less energy than the outer electrons. A consequence of the idea that there is less energy binding outer electrons to that nucleus is that it takes less energy to remove that outer electron from an atom. These are the so called ionization energies of the atom's electrons. And when the electron is in a higher orbital, it has a lower ionization energy. It can be removed more easily. As we attempt to remove more electrons from that atom, it takes progressively more and more energy as we move inward removing electrons.
Why alkali metal have low ionization energy?
Ionization energy is the energy required to remove an electron from an atom or ion. Low ionization energy indicates that it takes less energy to remove an electron from the atom. The alkali metals are in Group I on the Periodic Table. This indicates that their atoms have only one electron (out of a possible eight) in their outermost energy level. Therefore it takes less energy to remove the single outermost electron. Moving across a period on the Periodic Table, ionization energies increase because there are more and more electrons in the outermost energy level, requiring more energy to remove an electron.
How does the nucleus hold the remaining electrons after one has been removed?
More tightly. There is an electrical attraction between the positively-charge nucleus and the negatively-charged electrons. By removing an electron, the same positive force is now working on one-fewer electrons, so it is stronger, and it takes more energy to remove the second, and even more to remove a third, and so on...
According to bohr's theory of the hydrogen atom is it possible for the electron to orbit the nucleus with any possible energy?
It's actually completely opposite, electrons can have only specific energies (non-continuous) when the electrons are a part of an atom(s).
What evidence do scientists have that electron can move from one energy level to another?
It is a very simple observation to tell that an electron can drop from one energy level to another. Electrons always want to be at the lowest energy, but to get to allowed energy level they need to lose energy. Electrons release energy in the form of photons of the same amount of energy as the energy level change. We can observe the light released when we put energy into a system and match the energy of the light to steps an electron takes down the energy level.
What Energy is the energy that it takes to remove an electron from its shell.?
Ionization energy
Light is emitted as an electron transitions from a higher energy orbital to a lower energy orbital How long does it take for the actual transition to take place?
It takes no time as electrons can not exist in an inbetween state of charge
True or false the greater the distance of an electron from the nucleus the less energy it has?
Electrons exist in orbitals around the nucleus of an atom. It takes energy to knock an electron from the orbital it is in to an orbital a greater distance from the nucleus. The electron gives off energy when it falls closer to the nucleus. A Danish Scientist named Niels Bohr figured it out.
