Atomic Radius

Postby Jessica Helfond 2F » Sat Oct 27, 2018 1:07 pm

Could someone explain why removing the second ionization energy of an element is always higher than the first?

Since one electron has already been removed, the remaining electrons are now experiencing a greater attraction to the nucleus. The subsequent electrons being removed will have a higher ionization energy since they are less easy to remove.

When an electron is removed, the atom becomes a cation, or a positively charged ion. This positive charge in the atom makes the electrons more attracted to it, and therefore harder to remove.

There is less electrons to share the nucleus's positive charge once one of the electrons is removed, so the remaining ones have to take on more attraction to the nucleus .

When an electron is removed, the remaining electrons feel a greater attraction to the nucleus as there is more protons than electrons. This is makes it harder to take other electrons away.

There are fewer electrons that experience a greater force of attraction from the positive nucleus. Thus it is harder to take electrons away!

When an electron is removed, the proton:electron ratio heightens. Because of this, the surrounding electrons become more attracted to the protons in the nucleus, requiring more energy to remove said electrons and thus a higher ionization energy.

Removing an electron gives the atom a greater positive charge, converting it into a cation. This causes the remaining electrons to have a greater attraction to the nucleus.
