Ionization energy of an element is the energy required to ionize the element or in other words to eject a number of electrons from the most outer shell. For the first ionization energy it is the energy needed to eject 1 electron. Any ionisa...

Potassium (K). This one is easy b/c you can just look at the periodic trend. (lowest ionization energy would be the atom with the weakest bonding on the outer most atom due to distance from nucleus as well as shielding by other e's) So the ...

Because as the nuclear charge increases, the attraction between the nucleus and the electrons increases and it requires more energy to remove the outermost electron and that means there is a higher ionization energy. As you go across the pe...

The reason the second ionization energy is higher than the first relates to the attraction between the electrons and the nucleus. When one electron is removed from an atom, the neutral atom becomes positive. When one attempts to remove a se...

The first ionization energy pulls an electron away which makes the atomic radius of element strong, in turn making the the attraction between the nucleus and the electrons a lot stronger. This means that every time you remove an electron it...
