The atomic number is reminiscent of its protons, electrons, and neutrons during a neutral atom. When A particle of an atom contains 26 protons, 23 electrons, and also 56 neutrons.
Protons, Electrons, and Neutrons
When Every atom of tin has 50 protons in its nucleus. And there'll be 50 electrons around a neutral atom of tin. the quantity of neutrons varies because there are different isotopes of tin. Tin is interesting in this it's the element with the best number of stable isotopes of all the weather within the table. it's 10 stable isotopes, and that they are tin-112 (62 neutrons), tin-114 (64 neutrons), tin-115 (65 neutrons), tin-116 (66 neutrons), tin-117, (67 neutrons), tin-118, (68 neutrons), tin-119, (69 neutrons), The tin-120 (70 neutrons), tin-122 (72 neutrons), and also tin-124 (74 neutrons). There are other isotopes of tin starting from tin-99 to tin-137, and also the neutron count in any one of them are often found by subtracting the number of tin (which is 50, or the number of protons within the nucleus), from the mass unit of the isotope. for example, if we have an interest in tin-121, it's 121 minus 50 or 71 neutrons in it.
Thus the solution is 50
