Recall that the number of protons in the nucleus of an atom is called the atomic number, which uniquely identifies an element.
Look up the atomic numbers of the given elements: Indium (In), Tellurium (Te), Tin (Sn), and Antimony (Sb).
Compare each element's atomic number to the given number of protons, which is 50.
Identify the element whose atomic number matches 50, meaning it has 50 protons in its nucleus.
Confirm that this element is Tin (Sn), as its atomic number is 50.
