"D-block (for diffuse) elements consist of the transition metals (group 3-12 on the periodic table) in which the outermost electron shell is the D orbital. D-block elements form at least one stable ion with an incompletely filled electron subshell. "
That's not true, is it! E.g. the 3D-Block is in the fourth period, that means the outermost electron shell is the 4S orbital! I'll correct it. Hope everybody agrees.
Is ther a such thing as "25-block"?
New definition:
"The elements of groups 3-12 are the d-block elements. These elements are also commonly refererred to as the transition elements, though the elements of group 12 are not always included." —Preceding unsigned comment added by 83.79.50.183 ( talk) 20:18, 4 July 2008 (UTC)

Nice memory trick but it doesn't belong in the article. JIMp talk· cont 08:10, 25 October 2010 (UTC)
Are we supposed to know who this "Jensen" character is? The name is used in this article in 'Einsteinian' fashion. If you read an article about 'atomic orbitals,' I'm sure you would see the name Niels Bohr (with a link to his biography) first, before seeing the mononym 'Bohr.' Try doing a search on "Jensen." 64.180.243.107 ( talk) 23:36, 9 August 2012 (UTC)
Prof. Jensen is very well known in the inner circles of professionals who deal with issues pertaining to the periodic system of elements. I've corresponded with him myself, in fact. 69.121.117.192 ( talk) 05:50, 10 September 2012 (UTC)
In following text in the article, shouldn't the "across the periods" replaced by "across the groups"? Because "across the periods" means vertically not horizontally.
In the s-block and p-block of the periodic table, similar properties across the periods are generally not observed: the most important similarities tend to be vertical, down groups. However the d-block is notable in that horizontal similarities across the periods do become important. 111.118.41.122 ( talk) 20:43, 29 December 2012 (UTC)
