A With a Circle Over It Chemistry

A With a Circle Over It ChemistryA circle over it is a common diagram in chemistry, but it can also be called a circle of bases. This type of model can be used to show the basic four elements of atoms and molecular structures. The names for these elements are named based on the fact that they occur together.Oxygen is the most basic unit of chemistry. In this example the circle has been replaced by a star. Oxygen is not a primary element, however, which means that the star is also not composed of itself and so it would be incorrect to think of the circle as a diagram of the molecule's structure.Hydrogen is next. In this model the hydrogen atom is inside of the circle itself is inside of the hole. This method of showing the basic units of chemistry is somewhat misleading, as the star is actually formed from hydrogen and oxygen. Therefore, hydrogen is not included within the circle of bases at all.Chlorine is next. In this example the circle has been replaced by a star with a closed and a very thin upper ring. This is the same pattern as in the last example, where the circle has been replaced by a circle of bases. This example is a diagram of the chlorine molecule.The third element is sulfur. Here again the circle has been replaced by a star with a slightly different design. In this case the bottom of the star is green and the upper part is blue. The design does not actually reflect the atoms of the elements as sulfur is not a primary element in nature.The fourth element is carbon. In this example the circle has been replaced by a star with a narrow upper ring. Carbon is not a primary element, however, and therefore does not have an atom in the circle of bases. In this example the star is only a shape and the rings are built up of atoms of carbon.The fifth element is oxygen. In this example the circle has been replaced by a star with a wide ring. Oxygen is not a primary element and therefore does not have an atom in the circle of bases. The star is a shape and the rings are based on atoms of oxygen.A with a circle over it chemistry is often used to show the arrangement of atoms in a material or molecule. The rings are often modeled on the rings of a stone. The sequence of the ring shape tells you what element the material is made of.
