Everything around us is made of elements. Today, 118 elements have names. The periodic table lines up those 118 in order of atomic number.
Tap a colored square to open that element’s page. We begin with the 19 element symbols that Japan’s national curriculum guide lists as the basics for the second year of junior high school (about age 13–14), plus nihonium, the element made and named in Japan. Every page also gives the element’s name in Japanese.
