No, the isotopes of a single element differ in the no. of neutrons
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
number of neutrons = mass number - atomic number
Isotopes are atoms of the same elements with different number of neutrons.

Different elements with same number of neutrons are known as isotones.
atoms of different elements having same number of neutrons
neutrons of all atoms are alike
Atoms of the same element that have different numbers of neutrons are called isotopes. An isotope is known by its mass number, which is the sum of the protons and neutrons in its nucleus.
No, all elements have so called isotopes, meaning that the number of neutrons in the nucleus differs from the most common isotope. Hydrogen, for example, has three known isotopes: 11H, 12H, 13H, where the first one is the most common. They solely in their number of neutrons, not protons. The last two isotopes are less stable, hence less common.
No. Atoms differ in number of protons, neutrons and electrons.
The mass number of an element is equal to the sum of the elements neutrons and protons.
