Answers
Answer:
Hey mate here is your answer...
..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.
Elements combine to form chemical compounds that are often divided into two categories.
Metals often react with nonmetals to form ionic compounds. These compounds are composed of positive and negative ions formed by adding or subtracting electrons from neutral atoms and molecules.
Equation
Nonmetals combine with each other to form covalent compounds, which exist as neutral molecules.

Explanation:
Elements are substances (like hydrogen and oxygen) that can't be split into simpler substances.
A substance like water, that is made up of two or more elements, is called a compound. Compounds are usually very different from the elements that have combined together to make them.
