Rounak, the information can be Googled easily. For example, I can get the information from the following links (it's a good idea to cross-check across multiple sources): https://en.wikipedia.org/wiki/Indium https://www.hobart.k12.in.us/ksms/PeriodicTable/indium.htm which gives me the information, I am looking for. The symbol is In, the atomic number is 49 and the mass number (# of protons + # of neutrons) = 115. Is there anything specific you would like to know about Indium? Was the problem that you did not know what the definition of mass number is? Or was it something else?
