Want to learn more about one of science's heroes from history, Henry Moseley? Moseley solved one of chemistry's greatest puzzles - determining what distinguishes elements from one another and developed a means of identifying elements based on their atomic characteristics. Sadly he lost his life fighting at Gallipoli in WWI.

The metalloids have properties that are either a mixture of those common to metals and non-metals, or in-between the two. On the periodic table, they lie on either side of the dividing line between metals and nonmetals, and include boron, silicon, germanium, arsenic, antimony, and tellurium. While metalloids typically have a metallic appearance, they are usually too brittle to have structural uses. They can form alloys with metals, and they are found in biological agents, catalysts, flame retardants, glasses, optical storage and optoelectronics, pyrotechnics, semiconductors, and electronics.
The development of the semiconductor industry in the 1950s and solid-state electronics from the early 1960s both depended on the electrical properties of silicon and germanium.
Industrial uses of arsenic include alloys with lead (for car batteries and bullets) and gallium arsenide, which is the second most commonly used semiconductor after silicon. Use of arsenic in pesticides, herbicides and insecticides is declining due to its toxicity, and millions of people are affected by naturally-occurring arsenic contamination of groundwater.
