Ca21 stands for which term?

Explanation:
The symbol Ca with a 2+ charge denotes a charged calcium atom. Ca is the chemical symbol for calcium, and the superscript 2+ shows two positive charges, which defines the species as an ion. Put together, Ca2+ is the calcium ion. The other options don’t fit because they are distinct concepts: aspirin is a drug with a different chemical representation, left is a directional term, and liter is a unit of volume.
