First-year chemistry taught us lithium and magnesium show similar properties like forming nitrides and carbonates that decompose easily on heating. But I remember last summer helping my father measure the dropping well level with a *borewell*, and we used magnesium sulphate to soften the hard water—lithium would never be used like that on the farm. The book makes them seem like twins, but in practice, their costs and applications are worlds apart.
