[edit] Moved from ion article (to be integrated into this article)

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.

[edit] PoV

{{NPOV}} What's up with having a "A definition which is accepted for English A-Level exams" section? I don't even know what an English A-Level exam is. This is irrelavent. 20:49, 30 May 2006 (UTC)


There's a spelling error in the introduction of this article. It should be "bonded", rather than "bounded", I believe. For some reason I can't edit it.

[edit] "s orbital"?

I was reading the article and found "Particularly dramatic increases occur after any given block of atomic orbitals is exhausted, except when progressing to the next s orbital." Is it actually supposed to say that, or is that just a typo? In the event that it is supposed to say that, perhaps some sort of explanation as to what an s orbital is could be given to us shmucks out here? Much appreciated. 205.233.121.29 23:14, 8 March 2007 (UTC)

Although I am not able to put the phrase to layman's terms, the page on atomic orbitals will help. Starhood` 17:50, 2 April 2007 (UTC)

[edit] The variable n in Section `Electrostatic explanation'

If I understand the text correctly, the variable n in the section titled `Electrostatic explanation' has been used for two completely different quantities: First as the charge of the ion (+ne), and later on as the angular momentum number (n hbar). I am no expert on this matter, and I might be wrong, but I don't think that these two quantities necessarily equate to each other. For instance, you could have an electron in a hydrogen atom (ie, an electron around a proton, +ne = +1e) in an excited state, ie, in some shell with n > 1 in the Bohr model. Could someone more knowledgeable on this topic verify (or refute) this claim, and correct the text if necessary? 69.235.145.252 22:13, 1 April 2007 (UTC)

[edit] vertical or adiabatic?

Can somebody maybe briefly explain the difference between vertical and adiabatic ionization potential? Personally, I would be interested to know which of the two is generally measured experimentally... —The preceding unsigned comment was added by 131.169.252.37 (talk) 08:46, 16 May 2007 (UTC).








[edit] For better use==

If a chart of these first ionization energy can be provided in this page it would be more useful

Thank you
