The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

The periodic table of elements (often known simply as the periodic table) has been helping scientists with their work for a little over 150 years. The handy visual reference guide organizes known ...

Heavy ligands such as polyoxometalates are opening a new frontier in actinide chemistry. Studying materials that are both ...

This year we celebrate the 150 th anniversary of Mendeleev’s achievement in formulating the structure of the periodic table that we use today. He announced his structure in 1869, but the challenge of ...

In this edition of Celebrating Chemistry, explore atoms and the periodic table, go on an element scavenger hunt around your home, and try your hand at an elemental word search. Guide Linus—a lab ...

The ions formed have a full outer electron shell, so are very stable. See the study guide on groups in the periodic table for more information.

Electronegativity, an essential characteristic of all elements in the periodic table, measures an atom's ability to attract electrons towards itself within a chemical bond. This vital theoretical ...
