Indium Element Facts -

Indium is used in the production of low-melting alloys, typically with gallium. The melting point depends on the ratio of indium to gallium. An alloy with 24% indium and 76% gallium, for example, melts at just 16 o C. (4) This type of alloy can be used as a non-toxic alternative to mercury in some applications.

WebElements Periodic Table » Indium » electronegativity

The first scale of electronegativity was developed by Linus Pauling and on his scale indium has a value of 1.78 on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine). Electronegativity has no units but "Pauling units" are often used when indicating values mapped on to the Pauling scale.
