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.
The element Iodine has 53 protons, 53 electrons, and 74 neutrons
Indium: 49 protons/electrons, 66 neutronsTin: 50 protons/electrons, 69 neutronsAntimony: 51 protons/electrons, 71 neutrons
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.
Some paints may contain antimony in the form of antimony trioxide as a flame retardant. Manufacturers may use antimony compounds in paint formulations to meet fire safety regulations. However, not all paints contain antimony, so it is best to check the product's safety data sheet for specific information.
This isotope is antimony-123, which has 51 protons (atomic number) and 72 neutrons (mass number - atomic number). It is a stable isotope of antimony found in nature.
51 protons, 51 electrons and 70 neutrons (in Antimony-171 isotope)
Antimony has 51 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an antimony isotope = Mass number - 51
Protones = 51 Electrones = 49 Neutrones = 70 or 72
121Sb has 71 neutrons. This can be calculated by subtracting the atomic number of antimony (Sb), which is 51, from the mass number, which is 121.
Plutonium-239 has 145 neutrons.
