Actinium as on the
Check out Actinium on the
Periodic Table which arranges each chemical
element according to its atomic number, as based on the
Periodic Law, so that chemical elements with similar properties are in the
same column. Our Periodic Table is simple to use - just click on
the symbol for Actinium as on the Periodic Table for additional information and for an instant
comparison of the Atomic Weight, Melting Point, Boiling Point and
Mass - G/cc with any other element. An invaluable source of facts
and information as a Chemistry reference guide.
What is Actinium - IUPAC and the
Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985 and
now recognises more periods and elements than
Mendeleev knew in his day in his day but still all fitting into his concept of
the "Periodic Table" in which
Actinium is just one element
that can be found.
