1. Define atom, subatomic particle and molecule. List the subatomic particles, and describe their relative masses, charges, and positions in the atom. 2. Define atomic number, atomic mass, atomic weight, isotope, and radioisotope. 3. Explain the role of electrons in chemical bonding and in relation to the octet rule. Given the periodic table, be able to sketch the position and number of subatomic particles in an atom or ion. 4. Differentiate among ionic, covalent, and hydrogen bonds. 5. Compare and contrast polar and nonpolar compounds. 6. Draw several water molecules, label the atoms, bonds, etc., and explain how the structure of water results in its behavior. 7. From the periodic table be able to predict the number and type of subatomic particles in an atom or ion and the number of bonds it can form. 8. Diagram and explain how a salt such as NaCl (table salt) is formed from sodium and chlorine atoms. Diagram and explain how NaCl behaves in water
