Below are some objectives. Check if each objective possesses the SMART characteristics. If not, please suggest a revision for that objective. 1. know the meaning of atomic number and atomic mass 2. describe, on the molecular level, the effect of heating and cooling on the motion of molecules of a gas 3. identify different atoms 4. develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. 5. understand the formation of ions in ionic compounds
