An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
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.
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.
What is the xenon isotope mass number?
There are 9 isotopes, so there is no the isotope.

How many subatomic particles are in the element xenon?
The "subatomic" particles in atoms are usually considered to be only protons, neutrons, and electrons, although these may contain sub-subatomic particles such as quarks and gluons. Every atom of xenon contains 54 protons and 54 electrons, because 54 is the atomic number of xenon. Every atom of xenon also contains neutrons. The lightest naturally occurring and radioactively stable isotope of xenon is Xe-124. Since the mass number is the sum of protons and neutrons, the total of protons, electrons, and neutrons for this isotope is 124 + 54 or 178. The number of particles for any other isotope of xenon may be found by adding the mass number to the atomic number.

What is the mass number for Dy in chemistry?
mass number of dysprosium = 66 + number of neutrons in a specified isotope The mass number is different for each isotope.
What is the mass number of zirconium 98?
The mass number of zirconium-98 is 98 by definition: The number after a hyphen in the name of an isotope is the mass number of the isotope.

What are the number of neutrons in xenon?
Number of neutrons = mass number - atomic number.The number of neutrons for any element will depend on the isotope under consideration. The stable isotopes of xenon are124Xe,126Xe,128Xe,129Xe,130Xe,131Xe,132Xe,134Xeand136Xewith 70, 72, 74, 75, 76, 77, 78, 80 and 82 neutrons respectively.Note: atomic number of xenon = 54.
