Element
(It IS possible to alter elements by bombarding them with sub atomic particles and attempting to either augment or spilt the nucleus. Some elements are self-altering. These are the radioactive isotopes and they can change to several different elements before reaching their end state.)
Element. Known elements are represented on the Periodic Table of the Elements.
You can find a list of known elements on YouTube.com in a song by Tom Leher, but we have discovered a few more since it was performed (B&W).
Pure substances that cannot be separated into simpler substances are called elements.
A pure substance the cannot be separated into simpler substances by physical and chemical means is a chemical element.
The answer is: an element
A pure substance that cannot be chemically broken down into simpler substances.
A substance that cannot be broken down is a pure substance
Diamond. Diamond is composed strictly of carbon, covalently bonded to one another creating a covalent network, making it the hardest substance in the world. Also, graphite of your pencil is composed strictly of carbon, except that the structure is different than diamond.
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
!!A pure substance that cannot be separated or broken down into simpler substances by ordinary chemical means!!

An element is a pure substance that cannot be broken down into simpler substances by chemical means.
Not: atoms The answer is an element
An element.
Elements are pure substances that can not be separated into simpler substances by physically or chemical means.Compounds are pure substances composed of two or more elements that have been chemically combined.Mixtures are a combination of two or more substances that are not chemically combined.
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
Elements are neither. Elements, in the scientific sense, are configurations of atoms that form substances that cannot be separated into simpler substances. An example of an element is Hydrogen.
There are two types of substances: elements and compunds. Elements cannot be separated into simpler substances while compunds can. Take for example iron, pure iron is made of iron atoms, and they can't be divided into simpler substances, as such, iron is an element. On the other hand, salt is a substance that CAN be separated into sodium and chloride, so salt is a compound (and since sodium and chloride can't be furtherly separated they are elements). So, an element IS a substance, but not all substances are elements.
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
A pure substance cannot be separated into any other kinds of matter by any physical or chemical process. It is also made up of the same particles. An element is an example of a pure substance because it cannot be broken down into simpler substance.Examples of pure substances would be: H2O (water), neon (an element), and NaCl (table salt).a pure cickroach is gat with a goat
