Lithium be cut with a knife. When cut, it possesses a silvery-white color that quickly changes to gray as it oxidizes to lithium oxide. While it has one of the lowest melting points among all metals (180 °C), it has the highest melting and boiling points of the alkali metals. Lithium has a very low density (0.534 g/cm), comparable with pine wood. It is the least dense of all elements that are solids at room temperature; the next lightest solid element (potassium, at 0.862 g/cm) is more than 60% denser. Furthermore, apart from helium and hydrogen, it is less dense than
The Elements of Influence of Influence, a classification of the units of influence into an ontology. The Standard Table of Influence consists of 25 irreducibly unique influence stratagems (since revised down to 24, see below), organized by a three-class and eight-subclass superstructure. The table’s concise organization into a stable decision-support system for influence has led some practitioners to refer to it as “the Rosetta Stone of influence.” In addition to the Standard Table of Influence, "The Elements of Influence" details various other supporting tools and resources for the understanding and application of influence, including the Standard Cycle of Influence, Standard Factors of Influence, the
