Detailed explanation-1: -An element is a pure substance that cannot be separated into simpler substances by chemical or physical means.

Detailed explanation-2: -Elements are the simplest forms of matter and therefore cannot be broken down into simpler substances by any chemical or physical means. Elements are the building blocks for all other substances. Some examples of elements include hydrogen, oxygen, carbon, and sulfur.

Detailed explanation-3: -Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions.

Detailed explanation-4: -Elements are those pure substances that cannot be decomposed by ordinary chemical means such as heating, electrolysis, or reaction. Gold, silver, and oxygen are examples of elements.

Detailed explanation-5: -Elements are those substances that are composed of one kind of atom. They cannot be broken down into simpler types of matter by either physical or chemical means. They can exist as atoms (for eg: Neon) or molecules (for eg: Nitrogen).
