The subscript that is to the right of the element symbol, no subscript means 1. Example H2O, 2 hydrogen 1 oxygen
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
The subscript number after a chemical symbol indicates how many atoms of that element are present in a single molecule of the compound.
It is the subscripted number immediately after the chemical element symbol in the molecular formula. If there is no number, then only one atom of that element is in itExample:H2O means two H's plus one O in water,NH3 = one N and three H atoms in ammonia
No, the elements are not always in the same proportion. For example, two atoms of hydrogen combine with one atom of oxygen to make a single molecule of water. But one atom of hydrogen combines with one atom of fluorine to make a single molecule of hydrogen fluoride. The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.
Aluminum is not a diatomic molecule. As the term implies, a diatomic molecule is made up of only two elements which can either be the same or different.
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
Chemical Polarity refers to the separation of electrical charge within a single molecule composed of chemical elements. Carbon is a chemical element not a molecule.
The subscript number after a chemical symbol indicates how many atoms of that element are present in a single molecule of the compound.
indicate the number of atoms or ions in a single unit
A molecule may consist of atoms of a single chemical element, as with oxygen (O2), or of different elements, as with water (H2O).

We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
