The element Sn refers to tin, which has an atomic number of 50. The atomic number represents the number of protons in the nucleus of an atom. To determine the number of neutrons in an atom of tin, we need to know the specific isotope of tin being considered. Tin has multiple isotopes, which are atoms with the same number of protons but different numbers of neutrons.
The most common isotopes of tin are:
- Tin-112 with 112 neutrons
- Tin-114 with 114 neutrons
- Tin-115 with 115 neutrons
- Tin-116 with 116 neutrons
- Tin-117 with 117 neutrons
- Tin-118 with 118 neutrons
- Tin-119 with 119 neutrons
- Tin-120 with 120 neutrons
- Tin-122 with 122 neutrons
- Tin-124 with 124 neutrons
The number of neutrons in an atom of tin depends on the specific isotope. Therefore, you would need to specify which isotope of tin you are referring to in order to determine the exact number of neutrons.
