oxygen is an element not a molecular compound as a molecular compounds are chemically combined and are of more then one element.
Atomic mass of sodium is 23. The atomic mass of oxygen is 16. Therefore the molecular mass of sodium oxide is 23x2+16=62u.The atomic mass of oxygen is 16. Atomic mass of sodium is 23. Therefore the molecular mass of the given compound is 62 grams per mole.
Molecular
Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.
Atomic oxygen is many oxygen atoms (O). Molecular oxygen is lots of oxygen molecules which are each made of two oxygen atoms bonded together (O2).
Ionic Molecular
Carbon monoxide (CO) and carbon dioxide (CO2) are molecular compounds containing the elements carbon and oxygen. There is no compound named carbon oxygen.Added:Carbon is an element, atomic symbol C.Oxygen is an element, di-atomic molecule with symbol O2.Carbon dioxide is a compound with molecular formula CO2, where the two elements (C and O2) are bonded together.Carbon monoxide is a compound, (very different from carbon dioxide), with molecular formula CO, where the two elements (C and O2) are bonded together in a different way.
Since Oxygen exists in combined state in nature, it is termed as a molecular element and Sucrose is a molecule of Carbon, Hydrogen and Oxygen with no charge on it, hence it is considered a molecular compound.
Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g
SiF4 is a polar covalent compound
The atomic mass of I is 127. The atomic mass of F is 19. Therefore the molecular mass of the compound is 127+5x19=214u.
Carbon monoxide is a molecular compound because carbon and oxygen form a covalent bond with one another.
