We elaborate the uses of Calcium and atomic properties with characteristics. Calcium is a silver-white chemical element with atomic number 20. Its symbol is Ca and belongs to the group of alkaline earth metals and its usual state in nature is solid. Calcium is located at position 20 on the periodic table.
On this page you can discover the chemical properties of calcium and information about calcium and other elements on the periodic table such as magnesium, strontium, potassium or scandium. You will also learn what calcium is for and you will know what its uses are through its properties associated with calcium, such as its atomic number or the usual state in which calcium can be found.
You will see qualities of calcium such as its melting and boiling point, its magnetic properties or what its chemical symbol is. In addition, here you will find information about its atomic properties such as the distribution of electrons in calcium atoms and other properties.
For some elements, some of this information is unknown. In these cases we show the properties attributed to them.
The alkaline earth metals, among which is calcium, have properties such as being soft, colored and having a low density. Elements like calcium have low ionization energy. All alkaline earth metals form ionic compounds except for beryllium.
The state of calcium in its natural form is solid (paramagnetic). Calcium is a silver white chemical element and belongs to the group of alkaline earth metals. The atomic number of calcium is 20. The chemical symbol for calcium is Ca. The melting point of calcium is 1115 degrees Kelvin or 842.85 degrees Celsius or degrees Celsius. The boiling point of calcium is 1800 degrees Kelvin or 1527.85 degrees Celsius or degrees Celsius.
Calcium is a mineral that our body needs for its proper functioning and can be found in food. Through the following link, you can find a list of foods with calcium .
Uses of calcium
Calcium is a chemical element with the symbol of Ca and an atomic mass of 40,078. If you’ve ever wondered what calcium is for , here is a list of its possible uses:
- Calcium is used as a reducing agent in order to extract metals such as uranium , zirconium and thorium .
- Cheese is made through the use of calcium ions that coagulate milk.
- Cement and mortar, important mixes in building construction and other things, are made with calcium.
- Calcium hydroxide is used to determine if carbon dioxide is present. It is commonly used in science laboratories.
- Insecticides (chemicals that kill pests) are made with calcium arsenate.
- Aluminum , beryllium , copper , lead, and magnesium alloys are made using calcium.
- Calcium tungstate is used in glossy paints, X-ray studies, and fluorescent lights.
- Fireworks and flares can be made from calcium phosphide.
- The ice is removed from the roads using calcium chloride. It is also added to canned tomato and is a concrete conditioner.
- Calcium carbonate is used to make lime and limestone, which are two important compounds in the glass industry.
- Acetylene gas (used for welding) and some plastics are made from calcium carbide.
- Calcium gluconate is used as a food additive. It is also added to vitamin pills.
- The chalk is made from calcium sulfate.
- Calcium hypochlorite is used for swimming pool disinfection (kill bacteria) and is also a bleach. It is also added to deodorants and fungicides.
- Other calcium compounds are used in liquid fuels, textile production, dental products (including toothpaste), fertilizers, and the manufacture of yeast- based products .
Atomic properties of calcium
The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find calcium within the periodic table of the elements, calcium is in group 2 and period 4. Calcium has an atomic mass of 40,078 u.
The electronic configuration of calcium is [Ar] 4s2. The electronic configuration of the elements, determines the form in which the electrons are structured in the atoms of an element. The average radius for calcium is 180 pm, its atomic radius or Bohr radius is 194 pm, and its covalent radius is 174 pm. Calcium has a total of 20 electrons whose distribution is as follows: In the first layer it has 2 electrons, in the second it has 8 electrons, in its third layer it has 8 electrons and in the fourth one, 2 electrons.
