The Atomic Number is 51 and the mass is 121.76.
The element with a mass number of 52 could be tellurium (Te) or antimony (Sb). Both of these elements have isotopes with a mass number of 52.
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).
Element
An element's number of protons is the same as its atomic number. Thus, an atom with 51 protons has the atomic number 51. By looking up this element on the periodic table, one finds that it is antimony.
51 protons defines the element as antimony (Sb). It normally has 51 electrons, so with 52 electrons, it would be Sb with a 1- charge.
The element with an atomic number of 51 is Sb - Antimony; atomic weight = 121.75.
The element with a mass number of 52 could be tellurium (Te) or antimony (Sb). Both of these elements have isotopes with a mass number of 52.
Antimony is a meta element. Atomic mass of it is 122.
Corrected:V-51, Vanadium isotope (99.8%) has atomic mass of 50.94396 a.m.u. (mass number 51)Cr-51, chromium isotope is not a naturally occurring isotope, with atomic mass of 50.94477 a.m.u.Incorrect answer was:(Cr) Chromium (51.9961) has massnumber 52!!
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).
The element of Antimony (Sb) would have the atomic weight of 121.75.
Element
An element's number of protons is the same as its atomic number. Thus, an atom with 51 protons has the atomic number 51. By looking up this element on the periodic table, one finds that it is antimony.
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.
The chemical element that sounds like alimony is antimony. It has the chemical symbol Sb and an atomic number of 51.
51 protons defines the element as antimony (Sb). It normally has 51 electrons, so with 52 electrons, it would be Sb with a 1- charge.
antimony is found in over 100 minerals.antimony, the chemical element with the symbol Sb and atomic number 51
