what is the properties of Magnesium and beryllium
Answers
Answer:
Beryllium, Calcium and Magnesium are three of the six elements that fall into this category. The outer electronic structure of all these elements is similar due to which they all have similarity in their chemical and physical properties. They are all shiny, though fairly soft but still harder than alkali metals.

Answer:
Beryllium is the lightest of the entire alkali earth metal family. It was discovered by a French Chemist Louis-Nicholas Vauquelin (1763-1829) in 1798. He suggested the name glucinium, meaning ‘sweet tasting’, for the element because the element and some of its compounds have a sweet taste. The name beryllium was officially adopted in 1957 after the mineral beryl, which was the form of its discovery.
By far the greatest use of beryllium metal is in alloys (combination of two or more metals melted and mixed). Beryllium alloys are popular because they are tough, stiff, and lighter than similar alloys. Beryllium finds use in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools.
It occurs in about 30 different mineral species. One of the most important is Beryl (beryllium aluminium silicate). Emerald and aquamarine are its precious forms.
>The first person to recognise that magnesium was an element was Joseph Black at Edinburgh in 1755. He distinguished magnesia (magnesium oxide, MgO) from lime (calcium oxide, CaO) although both were produced by heating similar kinds of carbonate rocks, magnesite and limestone respectively. The name was coined from Magnesia. A pure, but tiny, amount of the metal was isolated in 1808 by Humphry Davy by the electrolysis of magnesium oxide.
Magnesium is used in products that benefit from being lightweight, such as car seats, luggage, laptops, cameras and power tools. Magnesium ignites easily in air and burns with a bright light; hence it’s used in flares, fireworks and sparklers.
Magnesium oxide is used to make heat-resistant bricks for fireplaces and furnaces. Also, Chlorophyll contains magnesium at its centre which enables plants to carry out the process of photosynthesis. Magnesium is very rarely found in the purest form. It usually occurs in a combined state in nature.
