What element has 51 neutrons?
Zirconium
as 40 protons and 51 neutrons in its nucleus giving it an Atomic Number of 40 and an atomic mass of 91. Zirconium is in Period 5 of the Periodic Table because it has 5 electron shells.
What is vanadium found in?

How do u find neutrons?
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons,
subtract the number of protons from the mass number
. number of neutrons=40−19=21.

Word origin:
Antimony was named after the Greek words anti and monos to mean “a metal not found alone.”
The chemical symbol, Sb, comes from the element’s historical name, stibium. Discovery: Antimony was a known metal in the 17th century and was likely used even earlier.
Vanadium atoms have 23 electrons,
28 neutrons
and 23 protons.
This tin atom has
50 protons, 69 neutrons
and 48 electrons. This is one of six stable isotopes of tin. This isotope can also be written tin-119.
The number of neutrons of xenon Xe is calculated as shown below. Therefore, the number of neutrons in xenon (Xe) is
54
. Note: In the nucleus, the number of electrons is the same as the number of protons for an atom.

Antimony (Sb). Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of antimony-122 (atomic number: 51), an isotope of this element. The nucleus consists of 51 protons (red) and
71 neutrons
(orange).
Although
antimony resembles a metal
it has poor electircal and conductive properties and does not react chemically like a metal and is classified as semi-metallic. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide.
The atomic number of Antimony is 51 and its symbol is Sb i.e. stibium. The electronic configuration of Sb will be 2,8,18,18,5. So, the number of valence electrons present in the outer shell of Sb is 5. Hence, the correct option is A
-5

Radium (chemical symbol Ra) is
a naturally occurring radioactive metal
. Radium is a radionuclide formed by the decay of uranium and thorium in the environment.
