Talk:Atom/Archive 1

message: I Have been wondering this. There cant be air, for air is consisted of atoms and we are talking about sizes smaller than the atom. There cant be nothing becouse, well, nothing dosn't exist. i have been told that a  Hipothetical vacuum, however the source is quite unreliable. Any thought on this?
Thank you.
:There is no space between the nucleus and the electrons. Check out the picture of the atom. The electron cloud fully fills the entire volume of the atom. -- Xerxes 17:39, 24 April 2006 (UTC)
thread_title: What is there between The Nucleus and the Electrons?

message: The atomic mass or nucleon number of an element is the total number of protons and neutrons in an atom of that element, - this is ambiguous and incorrect. The mass number or perhaps atomic mass number refers to the number of nucleons in a nucleus. The atomic mass refers to the actual mass of the isotope or to the average mass of all the isotopes. Atomic mass is equal to mass number only for C-12 by definition. Binding energy effects make the atomic mass for all other isotopes differ from their mass numbers. The atomic mass is used extensively in stoichiometric calculations as the atomic mass in grams of a mole of the substance. Mass number or nucleon number are distinct from atomic mass and useless in stoichiometric work. This needs to be rigerously applied to avoid confusion. -Vsmith 16:30, 2 Nov 2004 (UTC)
replies: text: Looking at the article on Periodic Table, possibly a link to (and expansion of) Primordial Elements might be appropriate. And further, to be consistent with the Periodic Table article, the value should actually be 83 naturally occuring elements (excluding synthetic and decay elements (the distinction actually is broken in the article)).

message: An automated Wikipedia link suggester has some possible wiki link suggestions for the Atom article, and they have been placed on this page for your convenience.Tip: Some people find it helpful if these suggestions are shown on this talk page, rather than on another page. To do this, just add  to this page. — LinkBot 10:37, 17 Dec 2004 (UTC)

message: Is there too much information on elements in the article (being redundant with
element)? This is an encyclopedia not a treatise/textbook (see WikiBooks) Dpr 03:36, 10 Mar 2005 (UTC)
thread_title:  Coverage of "Element" 

message: Could we also consider added a 'Also see' page. Because Atom also happens to be the name of a popular content syndication format similiar to RSS. --Mayuresh Kadu (India) 04:02, 20 Apr 2005 (UTC)
thread_title:  Also see 

message: There have been many good changes to the article today made by User:Voyajer.
However, the sentences about ions & about elements contribute to defining the limits of what counts as an atom. What counts as an atom is not just what particles it consists of, but that it be the smallest particle of an element. The contrast with ions helps make clear what, striclty speaking, does not count as an atom --JimWae 05:08, 12 December 2005 (UTC)
