The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.

Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
How much neutrons are in xenon?
Each isotope of an element has a different number of neutrons. Number of neutrons = Atomic mass of the isotope - Atomic number of the element The atomic number of xenon is 54. For the list of xenon isotopes see the link below.
How can you calculate the number of neutrons N in an atom?
equal to number of protons
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).
How do you find the number of nucleons?
To find the number of neutrons in an atom, first find the atomic weight of the element and round that number to the nearest whole number. Then, find the atomic number of the element. Subtract that number from the atomic weight and the number of neutrons will be found.
What element has the Same atomic number but different number of neutrons?
Almost all the elements have different isotopes having same atomic no but different mass no or neutrons.
How many neutrons dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
What equation is used to calculate neutrons for an element?
Number of neutrons = Atomic mass - Atomic number
What will be the no of neutrons protons of hg having mass no 200 atomic no 80?
The number of protons = the atomic number. The number of neutrons = the mass number - the atomic number Protons = 80 Neutrons = 120 Also, for extra information, not that you need it, the element would be mercury.
How do you calculate neutrons for elements in the periodic table?
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
How do you calculate the number of neutrons an atom of a specific element has?
First, find its atomic mass on the periodic table and subtract the number of protons (element number) from it and there you go
What is the number of neutrons for a specific element equal to?
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
How many neutrons are there in an element having a mass number of 52 and an atomic number of 22?
30. The Atomic mass is essentially the protons + neutrons. The Atomic number is the protons. Or the neutrons. Or even the electrons. With the exception of ions and isotopes, those numbers are all the same.
How many protons and neutrons in meitnerium?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons. Meitnerium has 109 protons.
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
How is the number of neutrons in an atom found?
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
How man neutrons dose uranium have?
Each isotope of an element has a specific number of neutrons (number of neutrons = atomic weight - atomic number).
