If a material cannot be separated into individual components by any chemical means, it is known as?

The term for a material that cannot be separated into individual components by any chemical means is called an element. Elements are the most basic form of matter and consist of only one type of atom. Each element has unique properties and cannot be decomposed into simpler substances through chemical reactions.

In contrast, compounds are substances formed when two or more elements chemically bond together, and they can be broken down into their constituent elements through chemical means. Mixtures are physical combinations of two or more substances that retain their individual properties and can be separated by physical methods. Atoms are the fundamental building blocks of matter and are the smallest unit of an element, but they can combine to form elements, compounds, or mixtures.
