Magnesium
Discovered by:
Sir Humphry Davy year 1808
Ionic or Covenalt bond or both
Magnesium is not a coveland bond beacuse it is metal,
but it is a inonic bond beacuse (ex.) magnesium and oxygeny
make ionic but if you add hydrogen it will become a covelant
bond, there for magneium is kind of both ionic and covelant. Magnesium is able to bond with one oxygen atom. The formula of the compund it MgO.
The word magnesium comes from the greek word Magnesia.
Atomic number: 12
Atomic mass: 24.31
Protons: 12
Electrons: 12
Neutrons: 12
Most common use:
Used in flares and pyrotechnics, including incendiary bombs.
It is lighter than aluminum, and is used in alloys used for aircraft, car engine casings, and missile construction .
Physical properties:
Magnesium is a shiny, silver or gray colored metal that is light in weight and strong.
The density of magnesium is 1.738 g/mL, which means the metal will sink in water, but it is still relatively light weight.
Chemical Properties:
Magnesium is a silvery white metal. The surface of magnesium metal is covered with a thin layer of oxide that helps protect the metal from attack by air. Once ignited, magnesium metal burns in air with a characteristic blinding bright white flame to give a mixture of white magnesium oxide.
Where can it be found?
It is more commonly found combined with other elements.
Safty
Eye contact: Flush the eye with plenty of water. If irritation persists call for medical help.
Skin contact: Wash of with water
If swallowed: If a significant amount of metal is swallowed call for medical help.
