What is the luster of MG?
Magnesium is a shiny, silver or gray colored metal that is light in weight and strong. Th density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight.
What color is magnesium?
In its elemental state it is a white-silvery solid (see coat color). Magnesium oxide powder is white (see dress color). Magnesium is also found in mineral salts, whose pointed protuberances are represented by the crown.
Why is magnesium shiny?
Characteristics and Properties It is a shiny gray metal which is most of the time covered with dull white color due to oxidation. The valence shell of magnesium contains only 2 electrons which makes it an electropositive element with an oxidation state of 2+.

What is magnesium good for?
Magnesium plays many crucial roles in the body, such as supporting muscle and nerve function and energy production. Low magnesium levels usually don’t cause symptoms. However, chronically low levels can increase the risk of high blood pressure, heart disease, type 2 diabetes and osteoporosis.
What did Joseph Black do to discover magnesium?
He found that with acids, magnesia alba behaved in a similar way to chalk (calcium carbonate), giving off a gas. He then heated a sample of the starting compound and found that the product, magnesia usta (now known as magnesium oxide), like quicklime (calcium oxide), did not effervesce with acids.
What is MG periodic table?
