The oxidation number of an element in this group can range from +3 to -2, depending on the group in which it is located. Helmenstine, Anne Marie, Ph.D. (2020, August 29). Potassium is a metal. A measure of the propensity of a substance to evaporate. Properties intermediate between the metals and nonmetals. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. -Most atoms have more electrons than protons. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. Its density is lower than water, which is 1.00 grams per cubic centimeters.
