Atoms are stable and self-stabilising 3D matter bodies that spin about their nuclear/atomic axes. Unless in extreme conditions or due to accidents, no part of an atom may be removed from it, and under no circumstances may additional parts be included in the structure of a stable atom. Atoms of all elements (except those of inert elements) have resultant external fields about them. Complimentary atoms arrange themselves to form groups until most of their resultant external fields are inhibited by the rotary motion of the atoms in planes across their atomic axes. Molecules form crystals and other groups in a similar manner for the same purpose. In order to form different combinations of atoms and/or molecules, it is necessary to break the present bonds between the atoms or between the molecules by varying their rotary speeds to enable their resultant external fields to be effective and form different kinds of groups (molecules, crystals, etc.). These actions are generally known as chemical actions.
