This is part of the article at en that hasn't been simplified yet.

For single atoms in a vacuum, there are physical constants associated with the process of ionization. The energy needed to remove electrons from an atom is called the ionization energy, or ionization potential. These terms are also used to describe ionization of molecules and solids, but the values are not constant because ionization can be affected by the local chemistry, geometry, and temperature.

Ionization energies decrease down a group of the Periodic Table, and increase left-to-right across a period. These trends are exact opposite of the atomic radius periodic trends. Electrons in smaller atoms are attracted more strongly to the nucleus, therefore the ionization energy is greater. In larger atoms, the electrons are not held as strongly so the required ionization energy is lesser.

The first ionization energy is the energy required to remove one electron, the second to remove two electrons, and so on. The successive ionization energies are always greater than the previous, and a certain nth ionization energy will be significantly larger than the rest. For this reason, ions tend to form with in certain ways. For example, sodium is found as Na⁺, but not usually Na²⁺ due to the large amount of ionization energy required. Likewise, magnesium is found as Mg²⁺, but not Mg³⁺ and aluminum may exist as an Al³⁺ cation.

Discussion: about the page List of ions[change source]

I think the page List of Ions should stay as a separate page. It contains much more information than the table of common ions in the page Ion. --Leiem (talk) 15:16, 4 February 2017 (UTC)[reply]

Why on Earth would we want more detail than En wiki? Macdonald-ross (talk) 15:20, 4 February 2017 (UTC)[reply]

I think the page could be a simple version, so that it can be written or translated into other languages. In zh-wiki, there is a full version of the list. Before I created that page, I was uncertain. But I find another page List of oxides, which doesn't has an en-wiki version either. --Leiem (talk) 15:33, 4 February 2017 (UTC)[reply]

Colour[change source]

Is this the correct word? Isn't colour usually spelled color? Is this page in a different kind of English than I use in Canada? 2604:3D08:BD80:CF00:90E0:790C:49FC:BB0E (talk) 23:39, 5 February 2024 (UTC)[reply]
