A substance that cannot be broken down into simpler substances by chemical reactions
The answer is: Element.
Chemistry is the study of matter and the changes it undergoes.
One of the most important aspects of chemistry is understanding which substances cannot be broken down into simpler substances through chemical reactions.
These substances, known as elements, are the building blocks of all other matter and can only be changed by physical processes.
Elements are made up of atoms, which are the smallest particles that retain their properties and cannot be broken down into simpler components.
Chemical reactions involve the rearrangement or transfer of electrons between atoms to form new compounds.
Since elements are made up of only one type of atom, they cannot participate in chemical reactions and thus cannot be broken down into simpler substances.
Understanding and learning about the elements is essential to understanding all other types of matter and chemical reactions.
