Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons in their nuclei. This results in isotopes having the same chemical properties but different atomic masses.
Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.
Isotopes of an element have the same number of protons in their nuclei (same atomic number) but different numbers of neutrons, resulting in different mass numbers. This difference in neutron content gives each isotope unique physical properties such as stability, radioactivity, and atomic mass.
Two atoms are isotopes if they have the same number of protons but different numbers of neutrons in their atomic nuclei. This results in atoms of the same element having different atomic masses.
Isotopes of an element have the same number of protons but differ in the number of neutrons. This gives them the same chemical properties, but different atomic masses. Isotopes also have different physical properties, such as stability and radioactive decay rates.
The nuclei of different plutonium isotopes all contain 94 protons, which define the element as plutonium. The isotopes differ in the number of neutrons they contain, resulting in different atomic masses for each isotope.
neutrons
Different numbers of neutrons in their nuclei.
isotopes
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons 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 are atoms of an element having different number of electrons.
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons in their nuclei. This results in isotopes having the same chemical properties but different atomic masses.
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.
neutrons
Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioactive and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.
12C and 14C are isotopes, meaning they are atoms of the same element with different numbers of neutrons in their nuclei. Isotopes have the same number of protons but different numbers of neutrons.
