The key term that corresponds to the definition “an atom that bears a charge as a result of gaining or losing valence electrons” is to be stated. Concept introduction: Metals have the tendency to lose electrons and non-metals have the tendency to gain electrons. This tendency of elements to lose or gain electrons depends upon the electronegativity and electronic configuration of the element. The species that is formed after gain or loss of electrons by the elements is known as an ion.

Sodium Borohydride Reduction (continued on the next page): 1. Draw the product of each of the reactions below and give the formula mass to the nearest whole number. ? (1) NaBH (2) acid (1) NaBD4 (2) acid ? 2. In mass spectra, alcohols typically break as shown in equation 8 in chapter 11 (refer to your lab manual). The larger group is generally lost and this gives rise to the base peak in the mass spectrum. For the products of each of the reactions in question # 1, draw the ion corresponding to the base peak for that product and give its mass to charge ratio (m/z). 3.
