They have different numbers of neutrons.
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
Isotopes, different neutron quantities.
No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.
Isotopes are elements that have the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. For example, Carbon-12 and Carbon-14 are isotopes of carbon.
They are called isotopes of the same element
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^
Yes, isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This is why the atomic mass on the periodic table is often listed as a range for an element.
The Proton number defines the element, so there cannot be two atoms of the same element with different proton numbers, because they will be, by definition, different elements. Neutron numbers can differ though. When one element has different neutron configurations, these are called Isotopes.

Atoms with the same atomic number (number of protons), but different mass numbers (i.e. different mass) are called isotopes. The difference in mass is due to different numbers of neutrons. For more info: http://en.wikipedia.org/wiki/Isotope
