    The universe consists of elements, basic substances that cannot be divided further. There are 118 elements in the world, and each has distinct characteristics. Together, they make up everything—air, water, life, and stuff. With the highest frequency on Earth, there is oxygen, silicon, and iron.

    It is hard to think that everything that is and everything that is created, can be broken down into elements. At is most basic, elements are pure substances that can’t be broken down into simpler substances. Then when elements are combined, everything is created. Basic elements are carbon, hydrogen, iron and oxygen. In lights, we can use argon and tungsten, in wiring we use copper, mercury can be used in some switches and thermometers, and water is obviously a need for all living life. Thank you for making this easy to understand
