A substance is any matter, any material which has mass and occupies space. As far as a specific substance, a material has a specific constitution.
An element is a pure substance which cannot be broken down into (or synthesized by) other substances.
For example, water is a substance, but water itself is the result of the union of two other elements, hydrogen and oxygen.
An element cannot be made by joining other substances together (example, gold).
A compound is a substance made up of two or more different elements chemically bonded together. A molecule is the smallest unit of a compound or an element that retains the chemical properties of that substance. An element is a pure substance made up of only one type of atom.
A molecule is a combination of two or more atoms bonded together, while an element is a pure substance made up of only one type of atom.
An atom is the smallest unit of matter that retains the properties of an element. A molecule is a group of atoms bonded together. An element is a substance made up of only one type of atom.
An atom is the smallest unit of matter that retains the properties of an element. An element is a pure substance made up of only one type of atom. A molecule is a group of atoms bonded together.

an atom is the smallest unit of an element, but an element is a pure substance
An element is a pure material substance, a convention is a meeting of people.
is this someone from 9I??
An atom is a particle the smallest of an element. An element is a substance made up of many atoms of ONE kind (or molecules consisting of two or more identic atoms)

A mixture is a substance composed of two or more components physically combined. An element is a pure substance composed of one kind of atom. A compound is a pure substance formed when atoms of two or more elements chemically combine.
A molecule is a combination of two or more atoms bonded together, while an element is a pure substance made up of only one type of atom.
An atom is the smallest unit of matter that retains the properties of an element. A molecule is a group of atoms bonded together. An element is a substance made up of only one type of atom.
A substance is matter that is uniform in composition. A substance can be an element or compound. A solution is another name for a homogeneous mixture. It is also uniform in composition, but a solution is made by physically combining two or more substances.
A chemical change can help you tell the difference between an element and a compound because an element is a pure substance that cannot be broken down or separated into other pure substances through chemical change while a substance that is made from two or more elements that have combined in a chemical change are known as compounds.
