Subscript: meaning, definitions and examples
🔢
subscript
[ˈsʌbskrɪpt ]
Definitions
mathematics notation
A subscript is a character or symbol that is written or printed below the normal line of type. In mathematics and chemistry, subscripts are used to denote the number of atoms in a molecule or to indicate the position of an element in a series. For example, in the molecular formula H₂O, the '2' is a subscript indicating that there are two hydrogen atoms in water. Subscripts are also common in indexing and reference systems, where they help in organizing information systematically.
Synonyms
Examples of usage
- The formula NaCl has a subscript of 1 for sodium.
- In DNA sequences, subscripts indicate specific positions of nucleotides.
- Subscripts are essential in chemical equations to balance the number of atoms.
