What is the subscript symbol for Fermium?
The chemical symbol of fermium is Fm; as a subscript in the isotopes symbols is atomic number.
Why does the symbol for oxygen not have a subscript?
The symbol for oxygen, O, does not have a subscript because oxygen is typically found as a diatomic molecule (O2) in nature. The subscript 2 is understood to represent the number of oxygen atoms bonded together.
Chemical symbol for Hellium?
He. Helium is a noble gas, meaning it is inert and cannot bond with any other atom.
The number placed below an elements symbol in a chemical formula is called a what?
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.

How many hydrogen atomes are present in one molecule of ammonium acetate NH4C2H3O2?
To answer this kind of question, all that is required is to add the subscripts that appear immediately after the atomic symbol of the atom in question, remembering that if there is no explicitly written subscript, a subscript of 1 is implied. In this instance, the symbol for hydrogen occurs twice, once with a subscript of 4 and once with a subscript of 3. Therefore, there are 4+3 or 7 hydrogen atoms in the formula unit.
