Document Summary
Chapter 2: you must understand chemistry to understand life: describe the difference between the terms element and atom . How does the valence shell relate to chemical reactivity of an atom: as a group, draw a venn diagram for the following terms: molecule, compound. Then place the following in the diagram: o2, nacl, h2o: discuss moles, atomic mass units, and avogadro"s number. Overview: in many ways, life can be viewed as a complicated chemical reaction. ); this is most familiar from the periodic table there are 92 naturally occurring elements, from hydrogen up to uranium. 4 elements (o, c, h, n) make about 96% of the mass of most living things. O o the number of units of a substance are described using the mole: molecular mass is the sum of the atomic masses of the atoms in the molecule. Chemical equations describe chemical reactions: reactants are written on the left, products are written on the right, an arrow (
