antimony (symbol Sb)
The element you are referring to is the element Antimony (Sb), which has an atomic number of 51 and belongs to period 5 of the periodic table.
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.
The fifty first element in the periodic table of elements is antimony, with the symbol Sb and atomic number 51.
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!!
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.
Sb is the chemical symbol for antimony, a metallic element located in group 15 of the periodic table. Its atomic number is 51. Antimony is commonly used in the manufacturing of flame retardants, batteries, and semiconductors.

The element with 51 neutrons is antimony (Sb), which is a metalloid. Being in period 5, it belongs to the transition elements in the periodic table, showing typical metallic properties and variable oxidation states in its compounds.
Antimony has 51 protons.
The isotope of zirconim, 91Zr, has 51 neutrons. In order to solve this problem, one must know that an element's atomic weight is the average of its number of protons and neutrons (only neutrons are variable). Since the atomic number is the number of protons, the atomic number subtracted from the atomic weight gives the number of neutrons. An element in period 5 that has this many neutrons is found to be zirconium (the isotope 91Zr).
