A substance that cannot be broken down into simpler substances by chemical means is classified as an element because it is comprised of only one type of atom. Elements serve as the fundamental building blocks of matter, and each element retains distinct chemical properties unique to its atomic structure. This inability to decompose into simpler forms distinguishes elements from compounds and mixtures, which can be chemically separated into their constituent parts.
This is the atom of a chemical element, unbreakable by chemical methods.
Substance A is likely an element, as it cannot be broken down by a chemical change. Substance Z is likely a compound, as it can be broken down by a chemical change into simpler substances. From this information, it can be concluded that substances A and Z have different chemical compositions and properties.
An element is a substance that cannot be split into simpler substances through chemical means. It is composed of only one type of atom.
An element cannot be separated into simpler substances by chemical means.
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
An element is a substance that cannot be further broken down into simpler substances by chemical means. Each element is made up of atoms with a specific number of protons in their nucleus, giving them unique properties and characteristics. Examples of elements include oxygen, gold, and carbon.
A chemical element, by definition.
