Brainpop Periodic Table Ws

The periodic table organizes all the known chemical elements according to their atomic structure. It categorizes elements based on properties of their atoms, which are made up of a nucleus containing protons and neutrons surrounded by electrons in shells or orbitals. The number of protons determines an element's atomic number and position on the periodic table, and gives each element its unique properties that distinguish it from other elements.
