The number of neutrons is different for each isotope.
The isotopes of the same element have an identical number of protons and electrons; the number of neutrons is different.
Isotopes : a different number of neutrons. The chemistry is almost identical (mainly the reaction times are slightly different.
neutrons
Isotopes of a particular element have the same number of protons but a different number of neutrons in their nucleus. This difference in the number of neutrons gives isotopes different atomic mass values.

Yes. An element is defined by its atomic number, the number, or the number of protons in its nucleus. When an atom has more or less neutrons it is still the same element, but a different isotope of that element.
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
Isotopes are different atoms of the same element with a different atomic mass. This difference is caused by a different number of neutrons.
The number of protons (and electrons in a neutral atom) is identical. The number of neutrons is different for each isotope.
IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
yes, protons affect which element an atom is. Each isotope of different elements has generally a different number of neutrons. Isotopes with the same neutron number are called isotones.
I'm assuming you ask about the situation when isotopes has the same atomic number but different masses; this is normal because the number of neutrons in the isotopes of the same element is variable. But the number of protons (identical to atomic number) remain constant.
