what is oxygen made of?

Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature. A rotating model of an oxygen molecule.

Molecular oxygen (dioxygen) is a diradical containing two unpaired electrons, and superoxide results from the addition of an electron which fills one of the two degenerate molecular orbitals, leaving a charged ionic species with a single unpaired electron and a net negative charge of −1.

All living organisms are composed of cells, from just one to many trillions. What are the ingredients for life? Your body is made mostly of three elements: carbon, oxygen, and hydrogen. Remember, an element is the simplest form of matter.

Oxygen is element No. 8 on the Periodic Table of Elements. ... Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth's atmosphere. Because it's all around, oxygen is easy to dismiss as dull and inert; in fact, it's the most reactive of the non-metallic elements.

An oxygen atom has a nucleus with protons and neutrons, and electrons that orbit around the nucleus. You can make a three-dimensional model of an oxygen atom with round objects; you can use Styrofoam balls, ping-pong balls, rubber balls or golf balls.

Answer and Explanation: The difference between air and oxygen is that oxygen is a pure chemical element, while air is a mixture, not an element. Oxygen just contains oxygen....

One mole of atoms of oxygen has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 1023 atoms of oxygen.

Composition of air Oxygen — 21 percent. Argon — 0.93 percent. Carbon dioxide — 0.04 percent. Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.

Compounds are made from two or more atoms chemically joined together. For example, water is a compound of hydrogen and oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom.

A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen O, or ozone, a molecule of three oxygen atoms, O3.

Air is mostly gas It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.

Methane and oxygen (oxygen is a diatomic — two-atom — element) are the reactants, while carbon dioxide and water are the products.

Oxygen. Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste.

Answer and Explanation: Oxygen has two unpaired electrons. Electrons in an atom can be identified in the shells.

Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.
