How Chemistry relates to our Career

1.       Why is chemistry important to your career?

The definition of chemistry is “The science that deals with the composition and properties of substances and various elementary forms of matter.” The importance of chemistry for my career is that it involves the process of how atoms and molecules interact with each other both at the atomic and larger scale. Chemistry also can be used for creating nanomaterials to be applied as a coating on consumer products.
