Antimony (Sb) is a Chemical Element with an Atomic Weight of 121.76 and Atomic Number of 51.
The element Sb is antimony. Its atomic number is 51, meaning it has 51 protons in its nucleus. The mass number of antimony can vary because it has several isotopes, but the most common isotope has a mass number of 121.
Antimony (Sb) has the atomic number of 51. The atomic number is the same as the number of protons in the atom (an the same as the number of electrons in the neutral atom).
Each neutral atom of antimony contains 51 electrons, the same as the atomic number of antimony.
the atomic radius of antimony is 159
You look up antimony. You discover its symbol is SB. You look on your periodic table. You come to the symbol SB. You see that it is number 51. You know that is also the number of protons in the atom. You know that 122 is the atomic weight. You know that the Atomic Weight mainly comes from the weight of the neutrons and protons. You know that when you have the atomic weight you can subtract the atomic number from the atomic weight and get the number of neutrons.
Antimony is a meta element. Atomic mass of it is 122.
The chemical element with the atomic number 51 is Antimony (Sb). Antimony is a Metalloid in Group 15(5) of the Periodic Table. It has 51 electrons in 5 electron shells with 5 electrons in the outer shell.
