When the same elements form compounds with different molecular forms, the compounds are known as isomers. (They may have different chemical properties.)
The name of a molecule with two sulfur atoms is "disulfur"
When atoms of different elements combine, they form molecules known as compounds. In compounds, atoms are bonded together through chemical bonds, such as ionic or covalent bonds, to create a new substance with unique properties.
The water molecule (H2O) is formed from atoms of hydrogen (H) and oxygen (O).
Two or more atoms of similar or different types combine to form a molecule. So, a combination of two atoms of oxygen is a molecule and not an atom. Oxygen is the name for both an element and a molecule. The molecule contains two atoms with a molecular fromula, O2 and is a gas at room temperature. The element oxygen or O is unstable and highly reactive. It is formed only briefly in some reactions.
the empirical formula and the molar mass
This sounds to me like you are wanting the term "molecule". A molecule is a group of atoms bonded together.
a molecule
Dinitrogen tetroxide.
Chlorine is an element, not a compound. Moreover, its a diatomic molecule, that is, a molecule of chlorine contains two atoms of chlorine.
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
There are 22 atoms in one molecule of Tylenol (chemical name: acetaminophen). This includes 9 carbon atoms, 8 hydrogen atoms, 1 nitrogen atom, and 4 oxygen atoms.
nitrogen dioxide has wo oxygen atoms in the molecule, this is given by the subscript 2 in the formula ((NO2) and di- prefix to oxide in the name.
