      Absolutely not! There really is no need. What is useful to know is how the periodic table is grouped together so that elements with similar properties are near each other. This helps you to make predictions

      No – that’s why it’s written down. If I’m ever doing a quiz I never get periodic table questions right. It drives my wife mad!
