Some years ago at the University of North Carolina at Chapel Hill, I taught a one-semester inorganic course for BS chemistry majors. During the class we covered all the noncarbon elements in a ...

We explore the science and chemistry going on inside Theo Gray's periodic table table. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells ...

Elements in group 1 and group 2 are metals. Atoms of group 1 elements have one electron in their outer shell, and atoms of group 2 elements have two electrons in their outer shell. Elements in groups ...

We look at the chemistry of gallium, the science behind the holes in the periodic table. We look at the chemistry of gallium, the science behind the holes in the periodic table, and the history of how ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

To honor women’s history month in the international year of the periodic table, today we wanted to share the story of two of chemistry’s most brilliant and bold women and their paths of elemental ...

Theo Gray collects elements and has put together this awesome Periodic Table Table. This week Reactions explores the science and chemistry going on inside this periodic table. Step into his office, ...
