Yes, it is possible; example for the mass number 234:
- uranium-234: 92 protons + 142 neutrons
- thorium-234: 90 protons + 144 neutrons
They are called as isotopes in which mass number differ by emmision of radiation
isotopes
Atoms of the same element have different isotopes, differing only in number of neutrons (so differing in mass number, atomic mass).
Isotopes are atoms of a given element that have the same number of protons but a different mass number and therefore a different number of neutrons.
Isotopes. They differ in the number of neutrons in the nucleus.
Atoms that have different mass numbers but the [same] number of protons are called isotopes.
Such atoms are isotopes and belong to the same element.
The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The atomic mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Isotopes.
