Not: atoms
The answer is an element
You a referring to atoms, or elements. Apart from breaking down into subatomic particle like neutron, protons and electron. They cannot be reduced to simpler substances.
A pure substances which cannot be broken down into simpler substances is an element.
pure substance that cant be broken into other substances is an element.
The answer is an element
An element.
an element
A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.
Because it cannot be broken down into a simpler substance by any substance and is composed of atoms that have the same number of protons in the nucleus. IN the case of gold that number is 79.

An element.
Carbon Monoxide (CO) is a pure substance because it cannot be broken down into any simpler structure.
A substance that cannot be broken down is a pure substance
A pure substance that cannot be chemically broken down into simpler substances.
Atom of carbon?
Only if it is a compound, as a compound is a pure substance that can be broken down into simpler pure substances by chemicalmeans. The decomposition of a substance is a chemical process that breaks down a compound into simpler substances or its constituent elements. So, by definition, the answer is yes. However, if the pure substance was an element, the answer would be no. An element is a pure substance that cannot be broken down into any simpler substances by chemical means. It is a pure substance in which every atom present has the same atomic number.
