The periodic table is like an exciting puzzle that many clever scientists worked on together! Here are some important people who helped create it:
Dmitri Mendeleev: He is often called the dad of the periodic table. He arranged elements based on their atomic mass. That means he looked at how heavy the atoms were.
John Newlands: He came up with the Law of Octaves. This idea showed that there are patterns in how elements behave. Just like music notes repeat every eight notes, elements have repeating properties too!
Henry Moseley: He made the table even better by focusing on atomic number instead of atomic mass. The atomic number is the number of protons in an atom.
These amazing scientists helped us understand elements better and made chemistry a lot more fun!
