That would be 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.
Robert Boyle
substances that cannot be chemically interconverted or broken down into simpler substances and are primary constituents of matter.
A pure substance that cannot be chemically broken down into simpler substances.
Elements are substances made of identical atoms which cannot be broken down to other substances. Matter is anything that occupies space and has mass.
An element cannot be chemically broken down into simpler substances. Elements are the simplest form of matter and are made up of a specific type of atom. Elements can only be transformed through nuclear reactions, such as radioactive decay or nuclear fusion.
Molecules of substances cannot be broken down unless through chemical means. The bonds between atoms in molecules are too strong to break apart through other means.
