Part A What statement best describes the atomic weight of an element? View Available Hint(s) What statement best describes the atomic weight of an element? Atomic weight is the sum of the masses of the isotopes. Atomic weight is the product of the relative abundances masses. Atomic weight is the sum of the masses of the isotopes multiplied by their relative abundances. Atomic weight is the masses of the isotopes less their relative abundances.

Oxidation States 12 of 14 > Neutral compounds In a neutral compound, the sum of the oxidation states is zero. Note that the sign of the oxidation states and the number of atoms associated with each oxidation state must be considered. In H20, for example, each hydrogen atom has an oxidation state of +1 and each oxygen atom has an oxidation state of -2 for a total nstant Oxidation states are important for keeping track of electrons in oxidation-reduction reactions....
