Physical properties

Magnesium is a shiny, silver or gray colored metal that is light inweight 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. Chemical Properties: Magnesium is a silvery whitemetal.


Calcium is a fairly soft metal with a shiny silver surface when first cut. The surface quickly becomes dull as calcium reacts with oxygen to form a coating of white or gray calcium oxide. Calcium's melting point is 850°C (1,560°F) and its boiling point is 1,440°C (2,620°F).

Chemical properties

  • Flame test:

Mg: White

Ca: Dark red

  • Burns with a bright white flame to give a white product (Magnesium oxide)

2Mg +O22MgO

  • Burns with a bright white flame giving a white product (Magnesium chloride)

Mg +Cl2MgCl2

  • Magnesium reacts slowly with cold water, forming magnesium hydroxide and bubbles of hydrogen:

Mg +2H2O Mg(OH)2+H2

  • It reacts vigorously if steam is passed over the heated metal, forming magnesium oxide and hydrogen:

  • Mg +H2O MgO +H2

  • Magnesium. Slight reaction. pH=9

MgO +H2O Mg(OH)2 t0C= 100-125°C.

  • 2Ca+O22CaO (calcium oxide)

  • Ca+Cl2CaCl2 (calcium chloride)

  • Ca + S = CaS (calcium sulfide)

  • Ca + H2 = CaH2 (calcium hydride)

  • Ca + 2HOH = Ca(OH)2 +H2 (calcium hyroxide)

  • 3Mg + N2 = Mg3H2 (magnesium nitrite)

  • TiCl4+ 2Mg = Ti + 2MgCl2 (magnesium chloride)

  • Mg + 2OH = Mg(OH)2 (magnesium hydroxide)

  • Ca + BeO = CaO + Be (calcium monoxide)

  • CaCO3 = CaO + CO2 (calcium monoxide and calcium dioxide)

  • CaO + H2O = Ca(OH)2 (calcium hydroxide)

  • Ca(OH)2 + CO2 = CaCO3 + H2O (calcium carbonate)

  • CaCO3 + H2O + CO2 = Ca(HCO3)2 (calcium hydrocarbonate)

Magnesium- Uses

  • Airplanes

  • Missiles

  • Flares

  • Bombs

  • Car Engines

  • Medicine

  • Computers

Calcium- Uses

  • Builds Strong bones and teeth

  • Used in Milk

  • Used to make plaster
