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

A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions‚ the London dispersion force and hydrogen bonding
