My Nucleus has 50 protons

I have ten stable isotopes each with 50 protons and neutrons ranging from 62 - 74.

I have 8 radiotopes, with half-lives ranging from 35 minutes to 10,000 years.

My average atomic mass is: 118.710 grams/mole

When neutral, I have 50 electrons. Here is my Electron configuration:

My Story

  • Discovered in ancient times by ancient civilizations.
  • earliest uses were to use with bronze.
My Jobs

  • used to coat other metals to prevent corrosion or other chemical action (tin cans are made from tin coated steel)
  • alloying agent, important alloys incldue soft solder, type metal, fusible metal, pewter, bronze, bell metal, Babbitt metal, White metal, die casting alloy, and phosphor bronze
  • the chloride (SnCl2.H2O) is used as a reducing agent and as a mordant in calico printing
  • tin salts sprayed onto glass are used to produce electrically conductive coatings. These have been used for panel lighting and for frost-free wind-shields
  • window glass is made by floating molten glass on molten tin (float glass) to produce a flat surface (Pilkington process)
  • a crystalline tin-niobium alloy is superconductive at very low temperatures. Such magnets, made of tin-niobium wire, weigh just a few pounds and produce magnetic fields that are comparable to that of a 100 ton electromagnet
  • trialkyl and triaryl tin compounds are biocides - there is concern over their environmental effects. Tributyltin is the active ingredient in a type of antifouling paint used on ships.
