What element is in period 5 and is a transition element and has 51 neutrons?

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).


What are the element number of neutrons?

Number of Neutrons = Mass number - Number of Protons


Finding the number of neutrons in an element?

To find the number of neutrons in an element, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). Neutrons do not carry a charge and help stabilize the nucleus of an atom.


How do you calculate the number of neutrons in cobalt?

The number of neutrons in any element is equal to mass number - atomic number. So,number of neutrons in cobalt is = 58 - 27 = 32. therefore, number of neutrons in cobalt is 32.


What is the number of neutrons of californium?

For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98


What is the number of neutrons for californium?

The number of neutrons is different for each isotope:Number of neutrons = Mass number of an isotope - 98


Where is the location of the neutrons in a periodic table?

Neutrons are not given directly on the periodic table. However the number of neutrons can be indirectly calculated. Mass number = Number of protons + number of neutrons


How can an atoms number of neutrons be determined?

Mass number-Atomic Number= Number of neutrons


What is the number of neutrons in phosphorus-31?

the number of neutrons is mass


Does carbon have the same number of protons neutrons and electrons?

Carbon has 6 protons an 6 electrons (in a neutral state). The number of neutrons is: - for 12C: 6 neutrons - for 13C: 7 neutrons - for 14C: 8 neutrons For artificila isotopes: number of neutrons = mass number - atomic number


To find the number of neutrons is an isotope start with the mass number and what?

The mass number of an isotope is the number of neutrons and protons in the isotope, let this be p +n = (mass number). To find the number of neutrons you need the atomic number (number of protons), let this be p. You then subtract the two: mass number - atomic number = no. of neutrons p + n - p = no. of neutrons = n


What is the average neutrons in ununpentium?

For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope – atomic number
