The number of neutrons is different.
There are about 33 isotopes of arsenic. Only one of them is stable, and that's 75 As 33. All the other isotopes are synthetic.
Neutrons.
They are called isotopes and the difference between different isotopes of one type of element is the amount of neutrons each have.
Isotopes of the same element, with different numbers of neutrons.
isotopes of a given element differ in the number of neutrons they have.

because they differ in the number of neutrons
They are called isotopes and the difference between different isotopes of one type of element is the amount of neutrons each have.
Atomsof the same element that have different atomic massesare isotopes of one another.
Most elements have different types of atoms. These variations on an element's atoms are called isotopes and have different numbers of neutrons and thus different atomic masses. It is also possible to artificially create other isotopes of elements that do not exist "naturally," even for the few elements that normally have only one isotope (e.g. gold, arsenic, cobalt, aluminum, phosphorus).
Isotopes of an element have the same number of protons but different numbers of neutrons. This results in variations in atomic mass for isotopes. The element atoms on the periodic table represent the average mass of all its naturally occurring isotopes.
Isotopes of the same element, with different numbers of neutrons.
isotopes of a given element differ in the number of neutrons they have.
Yes
They differ in their number of neutrons.Atoms of all isotopes of carbon contain 6 protons and 6 electrons.Carbon-12 is the most common isotope.Isotopes of an element differ because each isotope has a different neutrons, but the same amount of protons.Example: H-1H-2H-1 has 1 neutron, 1 proton, and 1 electronH-2 ,however, has 2 neutrons, 1 proton, and 1 electron.
Atoms of the same element can differ from one another in their atomic mass, which is determined by the number of neutrons in the nucleus. These variations are called isotopes. Isotopes of the same element have the same number of protons but different numbers of neutrons.
