Question

elements does not go through decomposition reaction why​

Answer 1

HELLO MATE

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B.

Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

if above characters are not there they won't involved in decomposition reaction.

Answer 2

Answer:

The simplest kind of decomposition reaction is when a binary compound decomposes into its elements. Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. ... A reaction is also considered to be a decomposition reaction even when one or more of the products are still compounds.
