element
a molecule
This sounds to me like you are wanting the term "molecule". A molecule is a group of atoms bonded together.
A particle made of atoms joined together is called a molecule. Molecules can consist of two or more atoms bonded together through chemical bonds.
The name of a molecule with two sulfur atoms is "disulfur"
Ozone consists of three oxygen atoms (symbol is O3).
The water molecule (H2O) is formed from atoms of hydrogen (H) and oxygen (O).
Most oxygen molecules are composed of two atoms of oxygen, and we frequently refer to oxygen as O2 (or O2) for this reason. Oxygen can also exist as the molecule called ozone, which is O3. Ozone is unstable, and will revert to O2 in a few minutes.
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.
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.
