It is definitely not a chemical compound. ★★★ Correct answer to the question: Is oxygen an element or a compound? It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. Table sugar, or sucrose, is a compound because it's formed when two or more elements are joined together. For example, two oxygen atoms may join to form a molecule, but they do not make a new compound. An element consists of only one kind of atom. Oxygen is amazingly reactive, so it is generally got here upon as a compound.

It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.After hydrogen and helium, oxygen is the third-most abundant element in the universe by mass. Today, there are about 118 elements in the known universe. In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei.Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by chemical means.The number of protons in the nucleus is the defining property of an element, and is referred to as its atomic number (represented by the symbol Z . Oxygen is both an element (O) and a compound (O2). It is relatively easy to identify a molecule of an element; all of the atoms in the molecular formula will be identical. Our high school chemistry program has been redesigned and updated to give your students the right balance of concepts and applications in a program that provides more active learning, more real-world connections, and more engaging content.
