The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.

∙ 11y agoThe mass number of an isotope is always the sum of the numbers of protons and neutrons in the each atom of the isotope. In this instance (54 + 79) is 133.

What is the number of neutrons in polonium?
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
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.
Is 18 O an isotope?
Number of Neutrons = Atomic mass minus Atomic Number. Neutrons = 18[Atomic Mass] - 8[Atomic Number] Neutrons = 10
What is the number of neutrons in the element radium?
How many neutrons does the most naturally occurring isotope of curium have in its nucleus?
Curium is an artificial chemical element. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; and atomic mass is 247 so no of neutrons is 151.
How can you dertermine the number of neutrons in a isotope?
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
How many neutrons in californium?
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
How many neutrons is in californium?
153 neutrons in the most stable isotope Number of neutrons = Atomic mass of an isotope - atomic number. Atomic mass of the most stable isotope of Cf is 251. Atomic number of Cf is 98.
Sn isotope of oxygen has an atomic number of 8 and an atomic weight of 18. how many neutrons does it have?
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons18 - 8 = 10
What is the neutron on zirconium?
Each isotope of an element has a different number of neutrons: Atomic mass of the isotope - Atomic number = Number of neutrons
What is the number of neutrons in rutherfordium?
The number of neutrons is different for each isotope. Number of neutrons = Atomic mass of an isotope - 104
What is the number of neutrons in polonium?
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
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.
How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
Is 18 O an isotope?
Number of Neutrons = Atomic mass minus Atomic Number. Neutrons = 18[Atomic Mass] - 8[Atomic Number] Neutrons = 10
What is the number of neutrons in the element radium?
How do you find the neutrons that are in the nucleus?
Number of neutrons = Atomic mass of an isotope - Number of protons (Atomic number)
