Chapter 2 (pp.31-44): Chemical Context of Life Learning objectives: 1. Know and be able to quantify the number of subatomic particles (main 3). 2. Explain the basis of reactivity of atoms. 3. Understand the basis of different chemical bonds and their relative strengths: 4. Define ‘chemical reaction’ (“rx”): (i.e., The making and/or breaking of chemical bonds.) 6. Know the meaning of “chemical equilibrium”. 7. Always remember: Molecules are 3-dimensional, and their ‘function’ is a direct consequence of their structure. Terms to know include: element, compound (cpd), atomic number & at. mass, isotope, potential energy, valence, valence shell, valence electrons, electronegativity, reactants, products, anion, cation, free radical … What do you know about an atom? Electrons go to the most stable position. Where there is low potential energy is where things tend to be most stable. First shell is the lowest energy level, the
