Users can now swipe and touch to access detailed information about each element, including its name, symbol, atomic number, atomic mass, Lewis dots, and radius. The table also incorporates color changes to indicate classification, melting point, boiling point, outermost orbital, radius, ion radius, electronegativity, and ionization energy. Additionally, temperatures can be displayed in Kelvin, Celsius, and Fahrenheit scales.

The updated version of K12 Periodic Table of the Elements includes the recently named elements Darmstadtium (110), Roentgenium (111), Copernicium (112), and UnunhexiumOn certain tablet devices, users can choose between traditional and expanded views of the table.
