BIOL 1201 : Biology Notes1 For Exam 1
Document Summary
Electronegativity how much an atom wants electrons (measure of attraction an atom has for electrons) --- electronegativity increases (going up) ^ electronegativity increases. Hydrogen bonds are like velcro one loop and hook is weak, but many together can become powerful. Water, for example, has a lot of hydrogen bonds. Weak attraction between atoms on different molecules or different parts of a large molecule. Occur between molecules that have polar covalent to ionic bonds. The oxygen molecule has higher electronegativity, so shared valence electrons spend more time around oxygen than around the. Oxygen is partial negative; hydrogen is partial negative. Cis-trans isomers (cis isomer, and trans isomer) (c254h377n65o75s6) The sum of the atomic masses for all of the atoms in a molecule. (remember total up the atomic masses of the atoms that comprise the molecule use molecular formulas) --- answer is expressed in.
