Detailed explanation-1: -In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchanging electrons between atoms.

Detailed explanation-2: -A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.

Detailed explanation-3: -Pure substances come in two different forms: elements and compounds. Elements are made of one type of atom, either by itself or bonded together to form a molecule. Compounds are molecules that are composed of two, simpler substances. They are made of more than one type of atom chemically bonded together.

Detailed explanation-4: -Mixtures are physical combinations of two or more elements and/or compounds. Mixtures can be classified as homogeneous or heterogeneous. Elements and compounds are both examples of pure substances. Compounds are substances that are made up of more than one type of atom.

Detailed explanation-5: -Elements and compounds are pure substances, but mixtures are not. Compounds are very different from the elements they contain.
