ionization

[Kaylee Clarke 1G]

Can someone please explain the concept of ionization? How do you know that ionization energy is based off the period table?

Ionization energy refers to the energy needed to remove an electron from an atom. When looking at a periodic table, ionization energies decrease down a group, as the value of n increases and electrons are further from the nucleus. Ionization energies also increase across a period, as the electrons are held more tightly to the nucleus.

Ionization energy is the energy required to remove an electron from the atom of a gas. The ionization energy is based off the periodic table because as you go from left to right across a period, ionization energy increases. The atomic number increases, so the atomic radius decreases since there is more protons pulling the electrons in. Thus, this makes it more difficult to remove an electron from the atom, so the ionization energy increases across a period. Moreover, it generally decreases down a group because as you go down a group, you go to a higher energy level. So, it is easier to remove an electron at the outer shells, which is equivalent to the decreasing ionization energy down a group.

Ionization energy is the energy needed to remove an electron from an atom. It has a trend in the periodic table because as you move across a period from left to right, the ionization energy increases, and as you move up a group the ionization energy also increases. It increases from left to right because as you move across the periodic table, the more positive the nucleus becomes as more protons are added and the atomic radius decreases, so the electrons are closer to the nucleus. As you move up a group, the ionization energy also increases because the electrons are closer to the nucleus as you move up. The atoms toward the bottom of the periodic table are very far from the nucleus and are therefore easier to remove.

Essentially, ionization is the energy required to remove an electron from an ion. For the most part, the trend on the periodic table is that ionization energy increases left to right and decreases top to bottom.

The highest ionization energy is at the top right of the periodic table and the lowest is at the bottom left. It is the amount of energy that is required to remove an electron from an atom.
