Dec 18, 2015· This project will deliver a recommendation in favor of the composition of group 3 of the periodic table as consisting either of. the elements Sc, Y, Lu and Lr, or; the elements Sc, Y, La and Ac. The task group does not intend to recommend the use of a 32-column periodic table or an 18-column.

Sep 15, 2015· The fifth idea in our series is the view that group 3 of the periodic table consists of Sc, Y, La and Ac. There is now enough evidence to show this is incorrect. In 1982, an article in the Journal of Chemical Education argued group 3 should instead consist of Sc, Y, Lu and Lr. 1 Some textbook authors have taken this up, but the majority seem ...

Periodic Table groups | Chemistry Nexus


In the standard form of the periodic table the s-block, p-block, and d-block elements are organised into 18 vertical columns called groups. These are labelled from 1 to 18 under current IUPAC numenclature. Earlier labelling schemes (Trivial Group names) For historical reasons some Groups have special names.

Talk:Periodic table/Archive 9 - Wikipedia


P.S. If you look at some historical periodic tables, you will find that the "*" under Y is sometimes explained as La and the following elements: so you can even argue that the form suggested is in fact a Sc/Y/La/Ac 32-column table, but with La and Ac put together with the (other) lanthanides and actinides, which are similar. No need to stretch ...

What seems to be lacking is a categorical criterion. 4 Once again the notion of trying to maximise the number of atomic number triads in the periodic table may provide such a criterion. Looking at the second choice of four elements, Sc, Y, Lu, Lr then the last three form a perfect triad.

Yttrium - Wikipedia


Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element.

The transition elements or transition metals occupy the short columns in the center of the periodic table, between Group 2A and Group 3A. They are sometimes called the d-block elements, since in this region the d-orbitals are being filled in, and are also referred to as B-group elements since in most numbering systems of the columns on the periodic table the numerals of these groups are ...

The periodic table of the elements by WebElements


The periodic table is an arrangment of the chemical elements ordered by atomic number so that chemical periodic properties of the elements (chemical periodicity) are made clear. There is no one single or best structure for the periodic table but by whatever consensus there is, the standard form used here is very useful and the most common.
