Magnesium complexes ensure the green color in plants and our body needs magnesium in bones, muscles and blood. In organic chemistry, magnesium compounds are known to every student as Grignard reagents, and in vehicle or aircraft construction, magnesium alloys ensure low weight.
The Magnesium video from the Periodic Videos series shows how magnesium was used as a flash in photo shoots.
Magnesium belongs to the 2nd main group of the periodic table, the group of alkaline earth elements.
The elements of the 1st main group of the periodic table are called alkali elements.
The alkali elements or alkali metals include lithium, sodium, potassium, rubidium, cesium, and francium. Together with hydrogen, these form the 1st main group of the periodic table. Hydrogen is not one of the alkali metals because it has completely different properties under standard conditions, i.e. under normal pressure and room temperature.
