elements
Substances that cannot be chemically broken down into simpler substances are called elements.
Those substances are called elements. Elements are pure substances made up of only one type of atom and cannot be further broken down or decomposed into simpler substances by chemical reactions.
That would be an Element.
Substances that cannot be split into simpler substances are called elements. Elements are the fundamental building blocks of matter and consist of only one type of atom. They cannot be broken down into simpler substances through chemical reactions. There are currently 118 known elements, each defined by its unique number of protons in the atomic nucleus.
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.
The breakdown of substances into simpler molecules is called catabolism. During catabolism, larger molecules are broken down into smaller ones, releasing energy in the process.
Atom of carbon?
This kind of reaction is called "decomposition".
Digestion is the process of breaking down food into simpler substances. Digestion is of two types: mechanical or physical digestion, and chemical digestion.
The process that releases energy to convert substances to simpler products is called catabolism. During catabolism, complex molecules are broken down into simpler molecules, releasing energy in the process which can be used by the cell for various metabolic functions.
Elements are substances made of identical atoms which cannot be broken down to other substances. Matter is anything that occupies space and has mass.
