Document Summary
Chapter 2 pages 20-32 review of chemistry. The atom is the smallest unit of an element that sill exhibits the elements properies. Atoms consist of a nucleus containing protons and neutrons. Surrounding the nucleus are a bunch of electrons. The atomic number of an atom is the total # or protons. Atomic weight of an atom is the total # of protons and neutrons. The element is determined by # of protons, isotopes of elements are determined by # of neutrons in the atom. The outmost energy level # of electrons decides how it will react with other atoms. Covalent bonds- the strongest chemical bonds, formed by sharing of a pair of electrons, rarely break covalent bonds can also have parial charges when the atoms involved have a diferent electronegaivity. Hydrogen bonds- formed when a hydrogen atom is shared between 2 molecules.
