A symbol with no subscript has an implicit subscript of 1, meaning one atom of that element per formula unit.
I'm not quite sure that's what you were asking.
The small number used to represent the number of ions of a given element in a chemical formula is called a subscript. Subscripts are written to the right of the element's symbol and indicate the number of atoms or ions present.
subscript
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.
The subscript indicating the number of atoms relative to a chemical symbol is located immediately after the chemical symbol and is written in a smaller font size at the bottom right corner of the symbol.
When counting atoms in a chemical formula, each element's symbol is followed by a subscript that indicates the number of atoms of that element present in the molecule. If there is no subscript, it is understood to be one. Parentheses indicate that the atoms within them are multiplied by the subscript outside the parentheses. For example, in the formula ( \text{Ca(OH)}_2 ), there is one calcium atom, two oxygen atoms, and two hydrogen atoms.
The small number used to represent the number of ions of a given element in a chemical formula is called a subscript. Subscripts are written to the right of the element's symbol and indicate the number of atoms or ions present.
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.
One (1).
The letter or letters that represent an element are called its atomic symbol. The numbers appearing as subscripts in the chemical formula indicate the number of atoms of the element immediately before the subscript. If no subscript appears, one atom of that element is present.
subscript
The subscript in a chemical formula refers to the number of atoms of that element present in the molecule. It is a small number written at the lower right of the element symbol. For example, in the formula H2O, the subscript 2 indicates that there are two hydrogen atoms in each water molecule.
In a chemical formula, a subscript is a number written to the right and slightly below the symbol for the chemical element. If the subscript is 1, it is not written. The subscripts for the chemical formula for water, H2O, are 2 for hydrogen and 1 for oxygen. The subscripts for the chemical formula for glucose, C6H12O6, are 6 for carbon, 12 for hydrogen, and 6 for oxygen.
The number placed below an element symbol in a chemical formula is called a subscript because it indicates the number of atoms of that element in a molecule or compound. The subscript is written slightly below the element symbol to differentiate it from the coefficient, which applies to the whole molecule or compound.
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
2, the subscript following the chemical symbol for chlorine in the formula.
There is one atom of that element in the molecule.
