Lab Report 4-Atomic Models, Bonding, and Isotopes Shelby Searles 03/07/18 Background: Atoms consist of positively charged composed of protons (+) and neutrons (neutral or no charge) that is surrounded by negatively charged particles called electrons. The atomic number equals the number of protons in the nucleus, Protons and neutrons in the center compose most of the mass of the atom. Protons and neutrons have a mass of 1 amu (atomic mass unit). So the mass number of an atom is the number of atoms + the number of protons. Protons give the atom its chemical identity whereas the electrons govern the atoms chemical behavior. Electrons are found at various energy levels in the electron cloud surrounding the nucleus. Electrons equal the number of protons to balance negative and positive charges in the atom. Electrons form bonds with other atoms by gaining, losing or sharing electrons to complete the outer energy level and thus become stable.

    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.
