The number of atoms is indicated by prefixes as mono, di, tri, tetra, penta, hexa, etc.
Examples: uranium hexafluoride - UF6, triuranium octaoxide - U3O8.
Argon is an element, not a molecule, and as such does not have a molecular formula, but rather a symbol - "Ar".
Nitrogen has a diatomic molecule (N2).
Chlorine is an element. Its diatomic molecular form is indicated by the symbol Cl2
I2 is a molecular element, not a compound.
Xenon (Xe) can be found on the periodic table in the far right column (Noble Gases) and is thus an element, not a molecule.
Argon is an element, not a molecule, and as such does not have a molecular formula, but rather a symbol - "Ar".
Nitrogen has a diatomic molecule (N2).
The molecular formula specifies the actual number of atoms of each element in a molecule.
Nitrogen is both an element and a molecule. In molecular form, Nitrogen forms a binary molecule N2 with a triple bond between the two Nitrogen atoms.
Sodium is a chemical element not a molecule; the symbol is Na.
Chlorine is an element. Its diatomic molecular form is indicated by the symbol Cl2
The molecular formula of a compound is the number of atoms of each element in one molecule. So in water (H2O), one molecule of water has 2 Hydrogen atoms and one oxygen.
Molecular hydrogen has two atoms, both which are of the same element - hydrogen.
molecular formula
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.
I2 is a molecular element, not a compound.
Xenon (Xe) can be found on the periodic table in the far right column (Noble Gases) and is thus an element, not a molecule.
