How do you think the scientists were able to organize and sort the periodic table of elements? (What do we know about elements, and how did that help them?)

Most non-metals were gases and liquids, brittle, and poor conductors of heat and electricity. Scientists then came up with the idea that they could arrange the element by the atomic mass number. Every element has its own unique atomic mass number because elements have different numbers of protons and neutrons.
