Calcium element has 20 protons, 20 neutrons and 20 electrons circling around. Calcium element is
vert important for the bone growth of animals.
Calcium is solid at room temperature. In the open air, calcium will act with oxgen to produce calcium oxide CaO.
The melting point
of calcium is 842 ̊C.
» Common Calcium compounds:
• Calcium Carbonate, CaCO3
• Calcium Hydroxide, Ca(OH)2
• Calcium Oxide, CaO
• Tricalcium Phosphate, Ca3(PO4)2
• Calcium Nitrate, Ca(NO3)2
• Calcium Phosphite, Ca3(PO3)2
• Calcium Sulfate (Gypsum), CaSO4
• Calcium Chloride, CaCl2
Example Reactions:
• Ca + 2H2O = Ca(OH)2 + H2
• Ca + 2HCl = CaCl2 + H2
• Ca + Cl2 = CaCl2
• Ca + H2SO4 = CaSO4 + H2
• Ca + O2 = CaO2
• Ca + CuF2 = CaF2 + Cu
• 2HBr + Ca = CaBr2 + H2
• Ca + Pb(NO3)2 = Pb + Ca(NO3)2
• Zn + Ca(NO3)2 = Ca + Zn(NO3)2
• Ca + CuSO4 = CaSO4 + Cu
