It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
The number of atoms of the same element in the molecule
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.
1Cl2 3F2 is not a valid chemical formula. In chemical formulas, the number comes before the element symbol, and subscripts are used to indicate the number of atoms present.
A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
Subscripts represent the number of atoms of an element in a molecule. They are written as small numbers to the right of the element symbol in a chemical formula. They indicate the ratio of elements in a compound.
The number of atoms of that element in the molecule
The number of atoms of the same element in the molecule
The subscripts in a chemical formula indicate the number of atoms of each element present in the compound. They show the ratio of the different elements in the compound's composition.
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.
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 chemical formula of a compound provides information about the elements present in the compound and the ratio in which they are combined. The subscripts in the chemical formula indicate the relative number of atoms of each element in a compound.
A subscript belongs immediately after the symbol of an element in a chemical formula to indicate the number of atoms of that element present in the compound. It is written as a small number at the bottom right of the element's symbol.
1Cl2 3F2 is not a valid chemical formula. In chemical formulas, the number comes before the element symbol, and subscripts are used to indicate the number of atoms present.
A chemical formula is a combination of symbols that shows the ratio of elements in a compound. Each element is represented by its chemical symbol, and the subscripts indicate the relative number of atoms of each element in the compound.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
They tell you how often an atom - or a group of atoms - are repeated.
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.
