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 alkaline earth metals are the second most reactive family of elements. Beryllium, magnesium, calcium, strontium, barium and radium are all shiny, and silvery-white. They all have low densities, melting points and boiling points, and they tend to form solutions with a pH greater than 7.
Beryllium is the only alkaline earth metal not to react with water. One of its naturally occurring compounds is emerald. Calcium is needed for healthy bones, and plants need magnesium to form the chlorophyll molecules they use for photosynthesis. Strontium is important to sea life, particularly for hard corals, which use strontium to build their exoskeletons.
Radioactive radium was discovered by Marie Curie and her husband Pierre, and was used in glow-in-the-dark paint until the 1960s!
Calcium is the third most abundant metal in Earth's crust and the fifth most abundant element. Pure calcium was isolated in 1808 by Humphry Davy, and is highly reactive. Calcium compounds have many industrial uses, including calcium supplementation in food and medicines - calcium ions are electrolytes, with a vital role in the physiological and biochemical processes of organisms.
