  Chemical element
A chemical element (sometimes called simply element) is a material that consists of atoms with the same number of protons in the nucleus.
For example, all atoms with 6 protons in their nuclei are atoms of the chemical element carbon, and all atoms with 92 protons in their nuclei are atoms of the element uranium.
Atoms of the same element whose nuclei contain a different number of neutrons are said to be different isotopes of the element.

 Knowing Synthetics are Elements
While it is true that in the early history of chemistry many substances that were deemed elemental turned out to be compounds that at that time simply could not be decomposed further into their elemental form, even then there were already many guides to deciding that a new substance was in fact elemental.
Moreover, the compounds that these heretofore undiscovered elements were expected to form could be predicted, and by using the available techniques for determining molar masses of molecules and elements, a new substance could be established as being of the appropriate mass to be a candidate for the missing element's spot on the periodic table.
An element is the simplest kind of substance, (not the "simplest form of a [specific] substance") A compound is a single substance made with two or more kinds of atoms.

 EPA: Federal Register: Mercury Switches in Motor Vehicles; Proposed Significant New Use Rule
Elemental or metallic mercury, which is a silver- white metal, is the pure form of mercury, not combined with any other elements.
Because it is a naturally occurring element, it is present in the environment from natural sources, such as weathering of rocks, as well as from anthropogenic (human) activities, such as industrial combustion.
Industries that use elemental mercury in their processes have had the largest occupational mercury exposure; however, the imposition of workplace exposure limits on mercury is expected to reduce worker exposure (Ref. 5).

Air elementals will react with deep respect or fear (depending on their personality) and will tend to obey the caster when in the caster's presence.
At the end of the spell's duration the elemental may vanish or may elect to stay on earth, no matter what kind of control the caster has on it (the caster can order it to leave before the spell is up, assuming he has controlled the elemental).

 Science 122, Program 23, Alchemy
Third, although crude, labors of alchemy sorted out processes and properties of substances (apparatus and manipulative techniques) which proved useful in chemical studies once the concept of weight was introduced late in the eighteenth century.
Substances were seen as having mystical properties, almost like personalities which were important in their use and in their reactions.
The elements were seen not as basic substances, but rather as substances which portrayed certain chemical or physical properties.

 Main Group Elemental Hydrides
The main group elements are then normalised to the corresponding main group elemental hydrides, a set that includes such well known species as: hydrogen, water, ammonia, methane, lithium hydride, xenon and hydrogen chloride.
Chemical elements symbols, such as Na for sodium and Cl for chlorine, are assigned to the element as basic substance.
The approach taken by the chemogenesis analysis is to saturation bond each of the first 36 main group elements with a common bonding partner, and then to explore the chemistry of the resulting binary compounds.

 Atoms - The Greek Atomistic Philosophy, The Rise of Experimentation, The Chemical Atom
Empedocles, thus, formulated the idea of an elemental substance, a substance that is the ultimate constituent of matter; the chemical elements are modern science's fundamental substances.
The composition of all compounds could be expressed in terms of the elemental substances, but it was the quantitative mass relationship of compounds that was the key to deducing the reality of the chemical atom.
The masses of the substances (in one liter) are the masses of equal numbers of molecules of each substance; the specific number of molecules is unknown, of course, but that number is unnecessary for the Cannizzaro analysis.

(b) Any radioactive substance, if, with respect to such substance as used in a particular class of article or as packaged, the director determines that the substance is sufficiently hazardous to require labeling in accordance with ORS 453.005 to 453.135 { - and 453.990 (2) - } in order to protect the public health.
However, the term 'hazardous substance' does not include any source material, special nuclear material, or by-product material as defined in the Atomic Energy Act of 1954, as amended, and regulations issued pursuant thereto by the Atomic Energy Commission.

 Atomic Theory
Although Democritus' ideas were to solve a philosophical dilemma, the fact that there is some underlying, elemental substance to the Universe is a primary driver in modern physics, the search for the ultimate subatomic particle.
It was John Dalton, in the early 1800's, who determined that each chemical element is composed of a unique type of atom, and that the atoms differed by their masses.
Such a relation for a substance is called its equation of state and is sufficient to describe its gross behavior.

 Prosperity by Charles Fillmore
Substance cannot be seen, touched, tasted, or smelled, yet it is more substantial than matter, for it is the only substantiality in the universe.
Substance is first given form in the mind, and as it becomes manifest it goes through a threefold activity.
Substance exists in a realm of ideas and is powerful when handled by one who is familiar with its characteristics.

 Science Summit, Brackebusch
This usage very clearly implies that elemental metal was dissolved, which is almost never the correct origin of metallic ions.
The claim by EPA consultants that the model, with the bioavailability variable set to 18 as determined in the "Box," predicts blood lead ion level in children in Wallace and Mullan is a clear indication to me that the model is faulty.
If the model produces good predictions of blood lead ion level in two different areas with widely different lead mineralogy while using the same bioavailability set-point of 18, the element of chance is the only logical explanation for the model results.

Section II provides information on three aspects of the carcinogenic assessment for the substance in question; the weight-of-evidence judgment of the likelihood that the substance is a human carcinogen, and quantitative estimates of risk from oral exposure and from inhalation exposure.
Epidemiologic studies failed to show a correlation between exposure to elemental mercury vapor and carcinogenicity; the findings in these studies were confounded by possible or known concurrent exposures to other chemicals, including human carcinogens, as well as lifestyle factors (e.g., smoking).
All of the studies have limitations that complicate interpretation of their results for associations between mercury exposure and induction of cancer; increased cancer rates were attributable to other concurrent exposures or lifestyle factors.

This elemental substance is made of very fine elementary living matter on the mental, astral and etheric levels, which is still in its involutionary process.
An important attribute of an elemental is that it has a sort of instinctive consciousness to stay together and to remain healthy, but also has an indescribable need for strong impulses, which stimulate its development to further materialisation.
The surprising paradox in the constitution of our physical, astral and mental bodies is, therefore, that they are built up of substances which are on the involutionary path and directed toward denser matter, while our innermost spiritual being, the higher self or the soul, wants to free itself from matter and evolve towards finer matter.
