The simplest type of substance is an element. They cannot be split up even by chemical reactions. There are over 100 elements, and the Periodic Table is a list of them.

An element is a pure substance that cannot be split into simpler substances by chemical means while a mixture is a combination of two or more substances
an element
If the above didn't answer your question, a substance that can be broken down into simpler substances is called a compound. Even the simplest compounds can be broken down into individual elements.
While some compounds do degenerate to their elements when heated, almost none do.
Element Compounds can be broken down to elements (atoms) which cannot be decomposed further into simpler substances (that's why they're called a-toms, from Greek 'à-tomos', meaning 'un-sliceable'.
!!A pure substance that cannot be separated or broken down into simpler substances by ordinary chemical means!!
Elements cannot be split using chemical reactions.
The short answer is 'nothing'. An element is a pure substance which cannot be made any simpler by chemical means. However, if we go beyond chemistry into nuclear physics, then heavier atoms split apart in the process of radioactivity, or can be made to split by neutron bombardment. For instance, if a uranium 235 atom is hit by a neutron, one way it can split produces barium and krypton.
An element is a pure substance made up of only single kind of atoms and it cannot be split up into simpler substances by chemical means. There are over 100 elements in this universe. All matters are made up of these elements. Elements combine chemically to form compounds. Ex: H- Hydrogen He- Helium O- oxygen.......etc.........
A chemical compound is a substance consisting of two or more different elements bonded together in a fixed mass ratio that can be split into simpler substances.
