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...

Nitrogen -Electron configuaration[He]2s 2 2p 3 has three electrons in individual 2p orbitals with aligned spins because electrons try and stay as far apart as possible. Oxygen -Electron Configuration -[He]2s 2 2p 4 must put 2 electrons in a...

a) Si ( ionization: increase from left to right and bottom to top of the periodic table) b) Sb (atomic radius: increase from right to left and top to bottom of the periodic table)
http://answers.yahoo.com/question/index?qid=20081003205...
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...
