CO2 is both a compound and a molecule.
Carbon dioxide is an inorganic gas (a gaseous compound or substance). CO2 is the chemical formula of carbon dioxide.
a molecule of an element (O2) or compound (CO2)
CO2 is the chemical formula of carbon dioxide. This molecule contain two elements, C and O.
compound
CO2 is both a compound and a molecule. It is a compound because it is made up of carbon and oxygen which have been chemically combined. It is a molecule because carbon dioxide exist as CO2 molecules, with simple molecular structure.
CO2 is Carbon dioxide, which is a compound that contains one atom of Carbon and two atoms of Oxygen in each molecule.
The Greek prefix used to represent the anion in the covalent compound CO2 is "di-" because there are two oxygen atoms in the molecule.
CO2 is a molecule. A molecule is a group of two or more elements binded together. An element is the thing that makes up the molecule. For example, the C in CO2 stands for Carbon, and element. And O stands for Oxygen, another element. The two means that there are two oxygen in this molecule.
H2O (water), CO2 (carbon dioxide) and N2 (nitrogen) are chemical compounds. O2 (oxygen) is a diatomic molecule, not a compound.
Co2 would be a diatomic molecule of cobalt (Co), but since cobalt is a metal it does not form molecules and is simply Co. CO2 is not an element but a compound of the two elements carbon and oxygen. It is carbon dioxide.
The subscript 2 shows the number of oxygen atoms in each molecule of the compound, carbon dioxide.
CO2 is a molecular compound, not an ionic compound. It consists of covalent bonds between its atoms (carbon and oxygen), rather than ionic bonds between metal and non-metal atoms.
