Mg 2+
This cation has already donated it's valence shell and would require that core electrons be pulled by a large ionization energy.

Would an electron have to absorb or release energy to jump from the second energy level to the third level?
Electrons are attracted to the nucleus of the atom of which they are a part; this is because of the electrostatic force between the negatively charged electron and the positively charged nucleus. Therefore it takes energy in order to pull an electron farther away from the nucleus and to enable it to remain at a greater distance. This is exactly the same phenomenon as raising a heavy object such as, let us say, a bowling ball, to a greater elevation. It takes energy to do it, since you have to overcome the force of gravity.
What is meant by the first ionisation energy of nitrogen?
THis is the energy required to remove(ionise) one (the first) outer most electron. For nitrogen this would be quite a large figure, because nitrogen, wants to accept electrons ,rather than remove electrons. As a general rule as you go along any given period, the ionisation energies increase. There are two 'humps', with a slight fall in ionisation energiers in this general increase.
Can atoms be ionized by being excited?
No. When you excite an atom, you just do something with the electrons within the atom. (You take them into higher energy levels.) An atom can be ionized only when it is charged, you would have to remove or add an electron. But you are only placing the electron on higher energy level, so it stays within the atom, therefore atom is not ionized.
What happens when a 3s electron becomes a 2s electron?
Any electron is not fixed to any sub-shell or orbital. If you provide sufficient energy to an electron, it would make transition to any of the higher energy orbitals and then come back to the lower orbitals radiating energy.
Which electron that would emit the greatest amount of energy by dropping electron levels?
N=2 To N=1 The greatest energy change comes between the lower energy levels.
What electron would require the least amount of energy to remove from the atom of sulfur?
This is an electron situated on the outermost level.
If enough energy was added to remove an electron for calcium which energy level would the electron be removed?
The 3s.
How Which element require the greatest amount of energy to remove an electron?
Core electrons. Probably the 1s level would require the most ionization energy to pull these electrons.
What electron transition would must likely require the absorption of energy with the longest wavelengths?
n=1to n=2
Is the potato the high energy electron?
yes, the potato would be the hgh energy electron
Why is it harder to remove an inner shell electron than a valence electron from an atom?
Electrons are attracted to the positive charge on the nucleus. The further an electron is found from the nucleus of an atom, the lower the force of attraction between it and the nucleus. Therefore an electron far away from the nucleus (like a valence electron) will have less of an attraction to the nucleus than one close to it. A lower attraction to the nucleus translates into the fact that less energy would then be required to remove the electron from the vicinity of that nucleus.
Why is the ionization energy needed to remove the first two electrons from Magnesium atoms relatively low?
magnesium has a 2 valence electrons. because the third electron is not a valence electron, or in the outer shell, much more energy would be needed to remove it

Would have to happen in order for an electron in energy level 3 to move to energy level 4?
The atom would have to absorb energy.
How can energy turn into matter?
You can remove energy from the matter by lowering its temperature.
Would you expect it to be harder to remove an electron from Na or O?
oxygen
What is energy released on adding an electron to an isolated gas phase atom?
All electron shells represent an energy level - it doesn't matter if its the outermost shell or not. In order for there to be a release of energy the electron has to be coming from a higher energy state. The only energy state higher than the outer-most electron shell would be a free electron. The only way an electron becomes a free electron is that sufficient was provided to lift it from what-ever electron shell (energy level) it was previously in to escape velocity. The energy that it then releases in returning is then this exact same amount of energy.
