How is lithium carbonate typically represented in prescriptions?

Lithium carbonate is chemically represented as Li₂CO₃. This notation indicates that each formula unit consists of two lithium ions (Li) paired with one carbonate ion (CO₃). The use of this formula in prescriptions is crucial, as it ensures clarity and accuracy for healthcare providers when dispensing the medication. Understanding the correct chemical representation helps in recognizing its properties, dosage formulations, and the way it interacts within the body as a treatment for mood disorders, particularly bipolar disorder.

The other choices do not accurately represent lithium carbonate. For instance, LiO₃ and LiCs imply different compounds and would not be appropriate for the context of lithium treatment. Similarly, LiCl refers to lithium chloride, which is distinct from lithium carbonate and used for different therapeutic applications. Therefore, the representation of lithium carbonate as Li₂CO₃ is essential for both proper medical documentation and effective patient care.
