. Its common oxidation number is +2. It is an alkaline earth metal.
Magnesium is the fourth most common element in the Earth as a whole
making up 13% of the planet's mass and a large fraction of the planet's
mantle. . Due to magnesium ion's high solubility in water, it is the third
most abundant element dissolved in seawater.](https://image.slidesharecdn.com/magnesio-130513171421-phpapp02/85/magnesio-1-320.jpg)
