The first five articles in my Elements of the Periodic Table series have been moved to pages on this site from their old home at Triond. The articles cover the following elements.

More elements will follow soon.

Boron

The fifth entry in my Elements of the Periodic Table series is boron. Boron was first isolated in 1808 by Sir Humphey Davy, in Britain, and Joseph-Louis Gay-Lussac and Louis-Jacques Thenard, in France, and is the first of the semi metals.

Although pure boron is almost chemically inert, its compounds have numerous uses. These uses are explored in the following article, along with the element’s history and production methods.

Beryllium

First isolated in 1828, beryllium is a brittle, grey alkaline earth metal and the fourth element examined in my Elements of the Periodic Table series. As in the previous three instalments of this series, I examine the history and uses of the element, including its use as a neutron source. Methods of extracting beryllium metal from mineral ores are also investigated.

Lithium

In the third of my Elements of the Periodic Table series I take a look at lithium. Discovered by Johan Arfwedson in 1817, lithium is a soft, shiny, silver-white alkali metal and the lightest of the solid elements.

The methods of lithium production, its history and the origin of its name are all discussed in the article. Also included are some of the uses of lithium, including batteries and, as lithium carbonate, as a treatment for bipolar disorder.

Helium

Gary Wallace — Sun, 23 Aug 2009 12:38:09 +0000

First observed by Pierre Janssen during a solar eclipse in 1868, helium is the second lightest of the chemical elements. In the second of my Elements of the Periodic Table series, the essential facts, history and uses of helium are examined, including its use as a coolant in the Large Hadron Collider (LHC) at CERN in Switzerland.

The article also discusses the methods of helium production and the origin of the element’s name. The properties of its two stable and four unstable isotopes are studied, including the superfluidity of helium-4.

Hydrogen

Discovered by Henry Cavendish in 1766, hydrogen is the lightest and most abundant of the chemical elements. In the first of a series of articles about the Elements of the Periodic Table, I set out to investigate the essential facts, history and uses of hydrogen.

On the way I look at hydrogen’s stable and unstable isotopes, the various methods of production (in industry and in laboratories) and the origin of the element’s name.
