To make it easier to keep track of essential elements needed in tree life, the entire periodic table of elements can be modified and truncated. Figure 1. This figure of tree essential elements demonstrate element relationships. Although each essential element in a family (each table column has similar electron shells and reactivity, each element is unique physically, as well as how its chemical properties in soil and within a tree are manifested. Essential element attributes make each usable for providing structures and biochemical functions in a tree. Basic chemical differences of essential elements are utilized by a tree to perform many essential functions.
