The definitive answer is 'Isotopes have a different numbers of neutrons'.
Taking hydrogen as an example. Iy has three isotopes.
#1 ; protium ; 1 proto and 1 electron 0 neutrons (The commonest isotope)
#2 ; deuterium ; 1 proton , 1 electrons 1 neutron. (Used to make ;heavy water')
#3 ; tritium ; 1 proton , 1 electron, and 2(TWO) neutrons. (Very rare and radio-active).
The isotopes of an element have the same number of protons, but different numbers of neutrons.
...electrons.Isotopes contain the same number of protons (hence, the same number of electrons) and electrons are what determine reactivity. 2nd answer : The isotopes have the same chemical properties because the electronic configuration of an element is same there fore isotopes posses the same chemical properties .
Isotopes are atoms with the same number of protons (same atomic number) but different numbers of neutrons, leading to different atomic masses. For example, carbon-12 and carbon-14 are isotopes of carbon with atomic number 6 but atomic masses of 12 and 14 respectively.
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
Isotopes are elements that differ in the number of neutrons they have. Isotopes of an element have the same number of protons in their nuclei but different numbers of neutrons, resulting in varying atomic weights.
The atomic number is the same for the isotopes of a chemical element.
The isotopes of an element have the same number of protons, but different numbers of neutrons.
If an atom of the same element has the same number of protons but a different number of neutrons, then they are isotopes.
All the isotopes of an atom have the same number of protons but different number of neutrons.
The isotopes of the same element have an identical number of protons and electrons; the number of neutrons is different.
Isotopes of an element have the same numbers of protons in the nucleus (and corresponding electrons). It's not so much "can have", as "do have". It's just a different number of neutrons that makes a different isotope.
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
Isotopes.
Isotopes are atoms of the same elements with different number of neutrons.
Isotopes of the same element have the same number of protons and electrons, but varied numbers of neutrons.
Isotopes. They differ in the number of neutrons in the nucleus.
Isotopes of the same element have a different number of neutrons.
