Calcium Research Paper

The mineral that is the most plentiful in the body is calcium. It is mainly found in bones and teeth but also in plasma and other fluids within the body. Calcium plays an important role in blood clotting, nerve transmission, muscle contraction and relaxation, cell membrane permeability and the activation of certain enzymes, along with protecting against colorectal cancer. The intake of calcium or dairy products is associated with lower blood pressures, controlling body weight and obesity.

Calcium plays a very significant role in our bodies. Approximately 99 percent of the calcium in our bodies is stored in the teeth and bones. Calcium generates about two percent of our total body weight. Calcium is crucial in bone formation, keeping strong bones and teeth and is known for helping to prevent osteoporosis. Although calcium is mostly thought about in the bones and teeth, it also plays important roles throughout the body. The amount of calcium outside the bones and teeth may be small in comparison to what is inside the bones and teeth, but is very useful in many functions in the body. Calcium is required in functions such as the contraction

6. The mass number is equal to an atom’s number of protons and neutrons added together.

Who discovered Calcium? Humphry Davy discovered Calcium in England in 1808 by electrolyzing a mixture of lime and mercuric oxide. The source name of Calcium is delivered from Latin ‘calx’ meaning lime, and the its symbol is Ca. It is silver colored, mainly hard metallic element that takes up approximately 3.5% of the earth's crust and is a basic component of most animals and plants. It occurs naturally in limestone, gypsum, and fluorite. The Physical and Chemical Properties are the characteristics of a substance, like Calcium, which distinguishes it from any other substance. Calcium is the 5th most abundant element on Earth but is very hard to extract,it takes up 4.15% of earth’s crust.Calcium is mainly found in Earth’s crust it becomes

The periodic table is a table that categorises and displays all of the chemical elements. It is made up of groups, periods and blocks. A group (also referred to as a family) are the columns of elements, there are 8 groups. The elements in each family have similar but not identical properties and they all have the same number of outer electrons. E.g. lithium (Li), sodium (Na), potassium (K) are all soft, white, shiny metals because they are all members of group 1. A period is each horizontal row of elements, there are 7 periods. In a period, the elements are not alike in properties, the first element in a period is always an extremely active solid, and the last element in a period is always an inactive gas. Properties change greatly across a given row. Each new period represents the next shell which electrons fill. A block is a region of the periodic, there are 4 blocks: S, D, P and F.

This widespread mineral can be found in human bones, comets, and all over the Earth in sedimentary, igneous, metamorphic, and hydrothermal rocks. It is the most abundant source of phosphorus and is involved in numerous industrial and scientific advancements.

What is Calcium? The chemical element Calcium (Ca) is a malleable, ductile, soft metal. It's located in period four and group two of the periodic table. Calcium atoms have 20 electrons and 20 protons, there are two valence electrons in the outer shells. Its mass number is approximately 40.08. Calcium has four stable isotopes including 40Ca, 42Ca, 43Ca, and 44Ca; 97% of naturally occurring calcium is in the isotope 40Ca. Isotopes are atoms that have the same number of protons and electrons, but a different number of neutrons. In nature, calcium does not appear as a metal itself instead it appears in the form of rocks and minerals such as limestone, dolomite, and gypsum. Calcium can be found in countries such as Russia, China, USA, and France.

Calcium is the most plentiful mineral found in the human body. The teeth and bones contain the most calcium. Nerve cells, body tissues, blood, and other body fluids contain the rest of the calcium. Calcium is one of the most important minerals for the human body. It helps form and maintain healthy teeth and bones. A proper level of calcium in the body over a lifetime can help prevent osteoporosis.

I am found in period 3 and group 2. My atomic number is 12, my atomic mass is 24.305 and I have five isotopes. My family is Beryllium, Calcium, Barium, Radium, and Strontium. What my family and I have in common is that we are all alkaline metals. Some of them are more reactive then I am be careful fellas.

My element is Cadmium whose chemical symbol is Cd. Its atomic number is 48. The average atomic mass for cadmium is 112.411 atomic mass units. It contains 48 protons and electrons, as well as 64 neutrons. Cadmium has nine stable isotopes. The nine

Magnesium is an element on the periodic table with an atomic number of 12 and an atomic mass of 24.305. Its complete electron configuration is 1s2, 2s2 2p6, 3s2. The most common ion formed from magnesium is Mg+2. Magnesium can be extracted from the minerals dolomite (CaCo3 MgCO3), carnallite (KCL MgCl2 5H2O), magnetite, olivine, and serpentine. It is most often obtained from seawater, in which each cubic kilometer contains about 1.3 billion kilograms of magnesium. It is also the third most abundant structural metal in the earth’s crust, exceeded only by aluminum and iron.

Calcium Homeostasis is the body’s way of maintaining calcium levels. This is important because calcium has some very critical functions for the human body. Some of those include electrical communication between nerve cells and electrical communication in muscle cells that allows us to move our muscles. A third extremely important function of calcium is the makeup of our skeletons, which gives our bodies structure. About 99% of all the calcium in our bodies is found in the skeleton. Because of these major functions, calcium is the most regulated mineral of our body, so much so that it has its own regulation system that is controlled by three hormones: PTH, Calcitriol and Calcitonin.

These so called “superheavy” elements, cannot be found in nature, instead they are created artificially by nuclear fusion. Therefore, and for the purpose of this activity, today I’m creating a new superheavy-undiscovered element and I’ll name it Danium.

My element is Boron. Boron compounds such as borax have been known and used by ancient cultures for thousands of years. Boron was first partially isolated in 1808 by French chemists Joseph L. Gay-Lussac and L. J. Thénard and independently by Sir Humphry Davy in London. Davy first tried to produce Boron by electrolysis of boric acid, but was not satisfied with how the results turned out. In 1909, American chemist Ezekiel Weintraub was able to produce 99% pure Boron, by reducing Boron halides with hydrogen. In 2004, Jiuhua Chen and Vladimir L. Solozhenko produced a new form of Boron, but were not certain of its structure. Boron is a tough element, very hard, and very resistant to heat. In its crystalline form, it is the second hardest element of all the

In living things, calcium is a component of leaves, bones, teeth, shell, and coral. Calcium plays a vital role in good health, although it is a biological significance came to be understood only during the late 19th Century. It is most abundant metallic element in the human body, embracing about 1.4% of body weight. 99.9% of the calcium in our body is stored in the skeleton (bones) and teeth. The rest of 1% circulates in the blood stream; this was proven by a biochemist Elmer McCollum in the early 1900s. Bones have 70% of the calcium by weight, which gives them their strength and rigidity. Calcium helps control contraction of the most essential muscle in the body- heart. A British physician Sydney Ringer discovered this he showed that heart
