Chlorine, Cl. Elements with the most ionization energy are located at the top right corner of the Periodic Table. As you travel down a period the ionization energy increases, whereas travelling down a group the ionization energy decreases.
Chlorine has a high ionization energy - 1251,2 kJ/mol for the first level.
The ionization energy would increase because the nucleus is going to pull the electrons tightly which will make it hard to lose an electron from an atom.
Ionization energy is more commonly used to remove the topmost electron in the atom very important information if you are getting ready for a test.
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.
This energy is called ionization energy and is different for each chemical element.

The second ionization energy is always greater than the first because once you have pulled off the first electron, you are now trying to remove the second electron from a positively charge ion. Because of the electrostatic attraction between + and -, it is more difficult to pull an electron away from a positively charge ion than a neutral atom.

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
The ionization energy of fluorine is 1681 kJ/mol (the first) and the ionization energy of iodine is 1008,4 kJ/mol.
Ionization energies are the amount of energy needed to remove an electron from an atom in the gaseous state, thereby giving the atom a positive charge and making it an ion. Ions get a +1 charge for each electron lost. It is this positive charge of the atom that makes the second ionization energy considerably greater than the first. Not only does the second electron have to overcome the initial attractive forces to nucleus, it must also overcome the extra +1 charge the atom has after the loss of the first electron, which simply takes more energy.
Ionization Energy is the energy required to remove an electron from an atom. In general, ionization energy increases as one approaches the upper right-hand corner of the periodic table.Sulfur is quite close to the upper right-hand corner, so it has a higher ionization energy. It is a non-metal, so it wants to accept electrons to fill its outer shell to the magic number of 8. Therefore, it is very difficult to remove one of its electrons.Magnesium, however, is a metal with two eletrons in its outer shell. Metals like to donate their electrons to reach an empty outer shell -- it doesn't even want the two electrons it has -- so it is quite easy to remove one.
Imagine that one electron has already been removed from an atom, the energy used to accomplish this is the 1st ionization energy. Now more energy is needed to remove a 2nd electron. That is the 2nd ionization energy.
Ionization energy is how much energy is needed to remove an electron from the valence shell (the outermost shell). When the atomic radius is smaller, you will need more energy to remove an electron because the pull from the nucleus on the electron is stronger. If the atomic radius is larger, then it will be much easier to remove an electron from the valence shell because there are more layers (shieldings) between the nucleus and valence shell.
