Indium is a soft, malleable post-transition metal used in touchscreens (ITO), solders, and semiconductors.

About Indium

Central to the touchscreens of modern devices, indium (In) is the transparent, conductive ingredient of indium tin oxide. Element 49 is a soft, malleable post-transition metal in group 13 of period 5, within the p-block, with an atomic mass of 114.82, the electron configuration [Kr] 4d¹⁰ 5s² 5p¹, and a Pauling electronegativity of 1.78. Beyond display coatings, it serves in low-melting solders and in compound semiconductors. A silvery, ductile metal, indium is solid at standard temperature and pressure, lies below gallium in group 13, and is soft enough to be worked with ease.
