The molecule can consist of atoms of the same element, or atoms of different elements. If you joined to molecules via covalent bonding, you'd have created a new molecule (it's nothing special) Compounds are (in the chemical sense of the term) made of two or more elements. This means a lot of molecules (like H2O) are considered compounds (though ...
Elements and Compounds. Element - An element is a substance composed of the same type of atoms (e.g. gold Au, oxygen O 2). Compound - A compound is a substance made of more than one type of atom (e.g. water H 2 O, carbon dioxide CO 2). Molecule - A molecule is the smallest particle of either an element or a compound.

Substances are a form of matter that has uniform and unchanging compositions. Salt is a substance. Water is a substance. Oxygen is a substance. Gold is a substance. All of these substances have static compositions. This quiz is over the division of matter commonly called substances. There are two kinds of substances: elements and compounds. When two elements get together they form a compound. For example, water has two atoms of hydrogen and one atom of oxygen. Atoms all have about the same size, but they have different weights. Plutonium is one of the heaviest atoms , about 200 times heavier than hydrogen , which is the lightest element.

    Atoms of different elements are different. (An atom of oxygen is different from an atom of hydrogen.) Atoms of different elements combine to form a compound. These atoms have to be in definite whole number ratios. For example, water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen (a ratio of 2:1). Three atoms Elements are combinations of atoms of the same element. Compounds are formed when atoms of different elements are combined.
