Sb (antimony)
Group 15 elements (N, P, As, Sb, Bi)
Sb (antimony) has 51 electrons. Its noble gas notation is [Kr] 4d10 5s2 5p3
36 + 2 + 10 + 3 = 51 electrons = 51 protons = Antimony (Sb)
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, symbol Sb has an atomic number of 51. This is the number of protons in the nucleus of an atom of Sb, and in a neutral atom it is also the number of electrons. The ground state electron configuration for antimony is: 1s22s22p63s23p63d104s24p64d105s25p3
The elements in group 15 Nitrogen, N; Phosphorus, P; Arsenic, As; Antimony, Sb and Bismuth, Bi all have a ground state with 3 unpaired electrons in p orbitals.
theatomic number of Antimony (Sb) is 51 and its atomic weight is 121.760. Determine the following: # The number of neutrons # the number of valence eletrons # the type of elementtheatomic number of Antimony (Sb) is 51 and its atomic weight is 121.760. Determine the following: # The number of neutrons # the number of valence eletrons # the type of element
Cl has 17I has 53 Xe has 54 and Sb has 51.
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).
Sb (antimony)
Sb (antimony)
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.
Sb has 5 valence electrons, In has 3, Rb has 1 valence electron and Xe has 8. So in ranking, it would be, Xe, Sb, In, Rb.
The valency of antimony is 5. This is because antimony is in Group V of the periodic table. Being a part of that group means that it has 5 valence electrons.
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.
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.
