Chemical Engineer The chemical engineer is an invaluable link between scientific principles and manufacturing realities. It involves the use of chemical‚ physical‚ and engineering principles. The scientist in a laboratory does basic research to develop new compounds and processes. When the scientist discovers a product that may be useful‚ the chemical engineer takes over. They adapt the product for big scale manufacturing. They do this by designing a plant to produce the item on large scale

Chemical Bonds Chemical Bond: is the force that holds atoms together in a compound. They form because they lower the potential energy of the charged particles that compose atoms. Chemical bonds can be broadly classified into two types: Ionic and Covalent. Ionic: metal & nonmetal Metals have a tendency to lose electrons and nonmetals have a tendency to gain them. The metal atom becomes a cation and a nonmetal becomes an anion. The oppositely charged ions attract one another and form an ionic

1. You don’t have to be a chem whiz * Chemical engineering requires a basic understanding of chemistry‚ physics‚ math. You’re not required to memorize formulas‚ it’s more important to understand the principles and learn how to apply them to solve a problem/improve status quo. However after a few semesters‚ your brain WILLremember many formulas! * You do need to be analytical and have the ability to think critically. You must be able to look at the problem from a bigger viewpoint but
