If you are not concerned about atoms, electrons, neutrons, protons and other sub atomic particles, but confine to chemical substances occurring in nature or man made, the substance that cannot be broken into simpler substances is an "element" (usually enumerated in a periodic table).A chemical element cannot be decomposed into a simpler substance.Elements. They are defined as substances in their simplest form and cannot be broken down or decomposed into any simpler substances. They include all elements in the periodic table of elements.
it is chemical property. they use the word decomposition immaterially shows changein chemical composition.hence chemical change.
No. Fe (iron) is an element, the simplest type of chemical substance possible, and so it cannot be broken down by chemical means.
chemical
The substance that can be decomposed by a chemical change is N2O (nitrous oxide) because it undergoes a decomposition reaction when exposed to heat or a catalyst, breaking down into its constituent elements nitrogen and oxygen.
The substance is a chemical element.
Ne - neon, is an element and also a noble gas. It can not be decomposed by a chemical reaction. All the other substances can be.
Carbon that cannot be decomposed is a chemical property. It is related to the chemical bonds and composition of the substance, indicating that the carbon atoms are tightly held together in a way that resists decomposition through physical means.
no
Rotting wood is a chemical change because the decomposed wood has different properties that cannot be reversed. Chemical changes alter the identity of a substance, whereas physical changes do not.

Wood. When wood burns, it undergoes a chemical change that breaks it down into ash and gas, releasing energy in the process. This decomposition by fire is a chemical change, transforming the wood into different substances.
No. Sodium is an element and elements cannot be broken down (decomposed) by a chemical change.
Octane is the only thing that can be decomposed by chemical means.
