About Periodic Table

Dmitri Mendeleev arranged the known elements by weight and repeating properties, leaving gaps where he expected undiscovered elements to fit. Modern tables order elements by proton count instead, with rows called periods and columns holding families like the noble gases, halogens, and alkali metals. Clues here reach across that grid: hydrogen at the top corner, mercury liquid at room temperature, tungsten with its stubbornly high melting point, and isotopes that share an element's identity while differing in mass.

Chemistry students and their teachers reach for this while reviewing element families, atomic structure, and the logic behind the table's layout.
