===About Mendeleev's Periodic Table===

: Scientists always try to look for patterns to help arrange complicated problems. Many different [[element]]s had been discovered so scientists wanted to arrange them based on patterns they noticed. Some scientists arranged them by patterns in [[Chemical Property|chemical properties]] while others tried to arrange them by patterns in [[Physical Properties]] like [[Melting Point]] or [[Relative Atomic Mass]].
