Antimony (symbol Sb) has three isotopes: 121Sb, 123Sb, and 125Sb. The 121 isotope has 70 neutrons, and the 123 isotope has 72 neutrons. The 125 isotope isn't stable and will decay, but it has 74 neutrons.

What element is period 5 element 51 neutrons?

An element with an atomic number of 51 and 51 neutrons is antimony (Sb). Antimony has an atomic mass of approximately 102, which is the sum of its protons (51) and neutrons (51). In the context of the periodic table, it is located in period 5 and group 15.


How many proton and electron in antimony 121?

Antimony, Sb, has the atomic number 51. The atomic number is the number of protons in the nuclei of all antimony atoms, so Sb atoms have 51 protons. In a neutral atom, the number of protons equals the number of electrons. So Sb atoms also have 51 electrons. Antimony-121 is an isotope of antimony with a mass number of 121. From the mass number, we can subtract the number of protons and get the number of neutrons in the atoms of the 121Sb isotope, which is 121-51 = 70 neutrons.
