Calcium is a soft gray alkaline earth metal, fifth-most-abundant element by mass in the Earth''s crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.
Calcium is one of the important elements on the earth. Here are Calcium Uses in Everyday Life like 1. Muscle contraction 2. In receptor function 3. In bone and teeth formation 4. In building material 5. In making Statues 6. In jeweller as pearls. etc.You will find all the
In Sections 1.3 and 2.5A3, we noted that the physical properites of a particular substance determine its state at room temperature.If both its normal melting point and its normal boiling point are below room temperature (20 C), the substance is a gas under
Calcium is a chemical element. Its syol on the periodic table (a list of all the elements) is Ca. Its atomic nuer is 20. (The atomic nuer says where Calcium sits in the periodic table.) It has 20 protons and 20 electrons (if is an atom, see ion). The most common isotopes are Ca-40 and Ca-44. Its mass nuer is about 40.08. Calcium is

The metal has a silvery color, is rather hard, and is prepared by electrolysis of fused chloride and calcium fluoride (to lower the melting point). Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame.
The boiling point is raised by 0.5 degrees Celsius for water with 29.2 grams of salt dissolved in each kg of water. If your concentrations of salt are different, then you can scale the boiling point elevation and melting point depression predictions directly with the
