Unstable isotopes can spontaneously undergo changes, transforming them into other isotopes of the same or of different elements. Stable isotopes do not. Some isotopes are very unstable and exist for less than a second; others can exist for billions of years but still be unstable. Many elements consist of more than one isotope. One or more of these isotopes may be unstable.
In isotopes of an element, the nucleus contains different numbers of neutrons while the number of protons remains the same and determines how the atom behaves chemically. There are several types of instability (too few neutrons, too many neutrons) and several types of decay.

∙ 13y agoIsotopes are atoms of the same element with different numbers of neutrons, leading to variations in Atomic Mass. Stable atoms have a balanced ratio of protons and neutrons, making them less likely to undergo radioactive decay. Isotopes may be stable or unstable depending on their specific composition.

Isotopes are atoms of the same element with different numbers of neutrons. Stable isotopes have a balanced number of protons and neutrons, meaning their nuclei do not decay over time. Unstable isotopes, also known as radioactive isotopes, have an imbalance of protons and neutrons, causing their nuclei to decay and emit radiation over time.
Isotopes of elements are atoms with the same number of protons but different numbers of neutrons. This causes isotopes of the same element to have different atomic masses. Isotopes can be stable or unstable, with unstable isotopes undergoing radioactive decay.
Isotopes are just the different possible nuclear weights of each element. Some are stable; some are unstable and radioactive. Since all atoms are isotopes and all isotopes are atoms, Isotopes can - and do - form ions, consequently they can have positive and negative charges.
Isotopes are atoms of an element that have different masses due to a different number of neutrons in their nuclei.

144Nd and 145Nd are isotopes because they have the same number of protons but different number of neutrons. Ce and Sm are different elements, so they are not isotopes of Nd.
Every atom of the same element is also categorized by its number of neutrons. An atom with a certain number of neutrons is an "isotope." Two atoms of the same element (same quantity of protons) can be different isotopes (different quantity of neutrons). Some isotopes are unstable, so most stable isotopes of an element are withing a range of a few numbers. For example, stable isotopes of carbon are Carbon-12 and Carbon-13.

No. There are different isotopes of lithium which have different numbers of neutrons and thus different masses. There are two stable isotopes of lithium: Lithium-6 with 3 neutrons and Lithium-7 with 4 neutrons.

No, atoms of the same element can have different numbers of isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, resulting in variations in their atomic mass.
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
Isotopes have the same number of protons but a different number of neutrons. Different isotopes of a single element are on the same position on the periodic table of elements. The existence of isotopes was first suggested in 1913 by a radiochemist named Frederick Soddy.
elements are isotopes, when different atoms of the same element have different number of neutrons
