Full chemical name of element: (Does it have a Latin origin)The full name of the element is calcium. Calcium comes from the Latin term calx, meaning lime. Chemical Symbol:The chemical symbol for calcium is Ca.Atomic number: Definition and numberCalcium’s atomic number is 20.The atomic number is the number of protons in an atom’s nucleus. The number of protons/atomic number determines the chemical properties of the element and where it is placed on the periodic table. Atomic mass: definition and massThe atomic mass of calcium is 40.078 AMU. The atomic mass of an element is approximately the total number of protons and neutrons in an atom’s nucleus. Atomic mass is measured by atomic mass units(AMU).Melting point:The melting point for calcium is 839?.Boiling point:The point at which calcium boils is 1,484?.State at room temperature: (solid, liquid, or gas)At room temperature, calcium is a solid.Who discovered it or isolated it? When?Humphry Davy discovered calcium in 1808.What does the pure element look like?The pure element calcium is a silvery white metal. Is it a metal, nonmetal, or metalloid?Calcium is on the left side of the periodic table, thus it is a metal. Where do you find it in nature? (on Earth)Calcium can be found in parts of the Earth’s crust. It makes up more than 3% of the crust and is the fifth most abundant element in the Earth’s crust. In nature, calcium is not found as a pure metal, instead it is found in limestone, gypsum, fluorite, and other minerals. Calcium also makes up leaves, bones, teeth, and shells.Identification of the element group and period:Calcium is part of Group 2 on the periodic table. This means that it is an alkaline earth element and contains 2 electrons in its outer energy level. As for periods, calcium is in Period 4. What is it used for?Calcium has many uses. First, metal is used as a reducing agent when extracting other metals, such as thorium and uranium. It is also used as an alloy agent, or hardening and strengthening agent. Calcium is combined to produce other metals such as aluminum, beryllium, copper, lead, and magnesium alloys. Although calcium can’t be found in a pure element state, its compounds are used in a variety of everyday things. Some examples include: Calcium carbonate, which is used to create cement, mortar, and glass; calcium carbide, used to make plastics and produce acetylene gas; calcium phosphate, put in animal feed and fertilizers; calcium gluconate, used as a food additive; calcium steerage, used to make wax crayons, cosmetics, plastics, and paints. Calcium’s biological role is essential to all living things. Most importantly, it helps the growth and strengthening of teeth and bones. When women are pregnant and children are growing, they are encouraged to eat foods rich in calcium to help them be healthy and properly grow. The compound calcium phosphate is what makes up our bones, thus people need to eat dairy products, leafy greens, fish, nuts and seeds to keep healthy levels of calcium. Interesting information:In nature, calcium can never be found isolated, or pure. It only exists within compounds. However, you can isolate the pure substance by extracting it through electrolysis. This process uses direct electrical currents to separate the elements within the compound. Once the element is isolated, it is highly reactive when exposed to air. The pure calcium will form a nitride coating, as well as a greyish-white oxide when exposed. There can be about two pounds of calcium in an adult body. This makes calcium the highest amount of the metallic elements in the human body.
