Bio 3: Homework #1 1. Hydrogen- 1 proton, 1 neutron, 1 valence electron Oxygen- 8 protons, 9 neutrons, 6 valence electrons Carbon- 6 protons, 7 neutrons, 4 valence electrons Sulfur- 16 protons, 14 neutrons, 6 valence electrons Nitrogen- 7 protons, 9 neutrons, 5 valence electrons 2. Ionic bonds are formed when there is an attraction between cations and anions. Hydrogen bonds form when a hydrogen atom covalently bonded to one electronegative atom and is also attracted to another electronegative atom. Hydrogen bonds can be described as molecular Velcro. Covalent bonds are the sharing of a pair of valence electrons by two atoms. A non-polar covalent bond is when the valence electrons are equally shared between the two atoms. A polar covalent bond is when the valence electrons are not equally shared. 3. Equilibrium is defined as the point when the rate of the forward reaction equals the weight of the reverse reaction. Reactants and products do not stop being produced at equilibrium because chemical reactions are reversible. At equilibrium, the products and
