The United Nations has declared 2019 the “International Year of the Periodic Table of the Chemical Elements,” to celebrate the 150th anniversary of the first periodic table and recognise the important role chemistry plays today in promoting sustainable development and providing solutions to global challenges.
Dimitri Mendeleev (1834-1907) created his early periodic table in 1869. He took the 63 known elements and arranged them into a table, mainly by their atomic mass. Although he wasn’t the first to do this, his interpretation involved a leap of ingenuity, in that he put those with similar properties below each other into groups and left gaps for new elements to be slotted in.
This has since formed the basis for scientists to search for or synthesise the missing elements. There are now 118 elements, laid out in order of increasing atomic number. There are repeating patterns in the properties of the elements, which give the periodic table its name.
Of course, modern chemistry has become about much more than the elements on the periodic table with complex formulations used every day in the manufacture of the products we consume.

RSL failures can be a costly burden for many manufacturers and it can damage relationships with brands and retailers. Without an effective chemical management system (CMS), it is likely manufacturers of material and/or product will experience compliance (RSL) issues relating to chemical failures. This will most likely be in highly...Published 2nd April 2019 Read more
