The content lists representative elements across key groups and periods, including Hydrogen and Helium, alkali metals such as Sodium, Potassium, Rubidium, and Caesium, and transition metals like Titanium and Vanadium. It also provides a legend explaining relative atomic mass and atomic number to support quick identification of each element’s key data.","THE PERIODIC TABLE  \n1 2 Group 3 4 5 6 7 0  \n© WJEC CBAC Ltd .
