It is 131.293
Xenon is a non metal element. Mass number of it is 131.
Xenon is a non metal element. Atomic mass of it is 131.
Xenon (Xe) is a nonmetalic gas. it has the atomic number of 54 with the atomic mass of 131.239.
The mass number of xenon is 131.
Xenon is a non metal element. Atomic number of it is 54.
The element with atomic mass 131 is Iodine (I)
54 protons in the element Xenon. Xenon has an atomic number of 54 and since the atomic number= number of protons there are 54 protons 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.
The sewyer was left open. End of story.
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.
The element with atomic number 54 is xenon. Xenon is a noble gas that is very unreactive. Because atomic number is equal to the number of protons in an element, xenon can be determined to have 54 protons.
Xenon is a metal element. Atomic mass of it is 131.29.
