Question

What problems could arise if every scientist used different symbols for the same element?

Answer 1

If every scientist used different symbols, scientists in different countries would not understand each other's notes, research papers, or chemical equations. The same element could be treated as two different substances, which may lead to errors in experiments and calculations. It would also become difficult to compare data and share information in books and databases. This is why IUPAC approves common names and symbols, so that chemistry can be communicated clearly across the world.
