The Chemistry of Life Chemistry is the study of the composition and structure of substances and the reactions they undergo. Basic Chemistry Matter, Mass, and Weight Matter is anything that occupies space. Mass is the amount of matter in an object, and weight results from the gravitational attraction between earth and matter. Elements and Atoms An element is the simplest type of matter with unique chemical and physical properties. An atom is the smallest particle of an element that has the chemical characteristics of that element. An element is composed of only one kind of atom. Atomic Structure Atoms consist of neutrons, positively charged protons, and negatively charged electrons. Atoms are electrically neutral because the number of protons in atoms equals the number of electrons. Protons and neutrons are found in the nucleus, and electrons are located around the nucleus, which can be represented by an electron cloud.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
