  1. Atoms and Elements Notes • What are the three parts of the atom and the charges they have? • Proton: positive charge (+) • Neutron: no charge (N) • Electron: negative charge (-)

  2. Atoms and Elements Notes • How do we interpret the numbers for each element on the periodic table? • Atomic number: # of protons in an element, this is what makes an element unique • Atomic mass: # of protons + # of neutrons • # of protons = # of electrons

  3. Atoms and Elements Notes • How can atoms vary, but still be the same element? • Isotopes: different number of neutrons • Ions: different number of electrons • cations have fewer electrons (positive charge) • anions have more electrons (negative charge)

  4. Atoms and Elements Notes • What is the Bohr model? • What are the different layers of electrons called? • What is the Octet rule? • a design of what the atom would look like • A shell is the “layer” of electrons • In order to have the shell be “full” it has the number of elements in that row on the periodic table

  5. Compounds and Mixtures • What is the difference between a compound and a mixture? • A compound is two or more elements that combine to form something new. • A mixture is two or more elements that combine and keep their original properties.

  6. Chemical Bonds • What is a chemical bond? • the way two elements attach together

  7. Chemical Bonds • What are the different types of chemical bonds? • Ionic bonds: where one element takes electrons away from another • Covalent bonds: where elements share electrons • Diatomic molecule: where two of the same elements bond together
