Mostelementson the periodic table are metals and have the-iumsuffix. Halogen names usually end with-ine, and noble gas names usually have the-onending. Elements with names not following these naming conventions tend to be onesknown and discovered long ago. Future Element Names Right now, the ...
The lanthanides or lanthanoid series isa group of transition metalslocated on the periodic table in the first row (period) below the main body of the table. The lanthanides are commonly referred to as the rare earth elements (REE), although many people group scandium and yttrium together under...
Platinum appears next to gold on the periodic table. It has the atomic number of 78. It is abbreviated as 'Pt.' It is also sometimes used in medicine for cancer. This non-ferrous metal is very similar to silver in color and luster but it is not as precious. It is often used in al...
The first chemical element is Actinium and the last is Zirconium. Please note that the elements do not show their natural relation towards each other as in the Periodic system. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides...
