If you are not concerned about atoms, electrons, neutrons, protons and other sub atomic particles, but confine to chemical substances occurring in nature or man made, the substance that cannot be broken into simpler substances is an "element" (usually enumerated in a Periodic Table).
A chemical element cannot be decomposed into a simpler substance.
Elements. They are defined as substances in their simplest form and cannot be broken down or decomposed into any simpler substances. They include all elements in the periodic table of elements.
Elements (such as oxygen and carbon) cannot be decomposed by a chemical change. Only compounds can be decomposed by a chemical change, becoming simpler compounds or single elements.
which substance can not be decomposed by a chemical change? what is the formula?
Argon
A chimical property that indicates weather a substance can undergo chimical change
chemical property.
The chemical property of a substance relates to its ability to undergo a change. It transforms the substance into different substances.
The initial substances in a chemical reaction are called reactants.
Oxidation is a chemical reaction; but a physical modification can also occur.
The ability of a substance to undergo a chemical change is called the Chemical activity of a substance.
A chimical property that indicates weather a substance can undergo chimical change
This ability is called reactivity.
chemical property.
Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
Water is not a change of any sort. It is a substance. It can undergo physical and chemical changes.
The chemical property of a substance relates to its ability to undergo a change. It transforms the substance into different substances.
When one substance or combination of substances undergo change to become another substance or substances
The initial substances in a chemical reaction are called reactants.
Oxidation is a chemical reaction; but a physical modification can also occur.
its chemical property is the reason why such a substance change,due to different processes it can form again a new substance
Catalysts doesn't undergo a chemical change during a chemical reaction.
