Isotopes of the same element differ in the number of neutrons. Isotopes of different elements differ in the number of protons and neutrons.
For instance, carbon-12, a stable form of carbon, has 6 protons and 6 neutrons. Carbon-14, a radioactive form of carbon that occurs in nature, has 6 protons and 8 neutrons. Nitrogen-16, on the other hand, also radioactive and occurring in the primary coolant of nuclear power plants, has 7 protons and 9 neutrons.
Uranium isotopes
Isotopes are atoms of the same element which differ in the number of neutrons they contain. For example, helium-3 (3He), with two protons and one neutron in each nucleus, and helium-4 (4He), with two protons and two neutrons, are two different isotopes of helium. Nearly all elements found in nature are mixtures of several different isotopes. Although the chemical properties of isotopes of the same element are the same, the physical properties differ. The natural proportions of the isotopes are expressed in the form of an abundance ratio.
The two isotopes of chlorine are the same in that they have the same number of protons, which is the atomic number. The neutral atoms of each isotope also have the same number of electrons as protons. They differ in the number of neutrons.
To calculate the relative abundance of two isotopes, you would divide the abundance of one isotope by the total abundance of both isotopes and then multiply by 100 to get a percentage.
Oxygen with 8 protons and 8 neutrons is the stable isotope oxygen-16. The rare form with two extra neutrons is the isotope oxygen-18. Both isotopes have the same number of protons (8) but differ in the number of neutrons, resulting in different atomic masses.
Uranium isotopes
False. Carbon-12 and carbon-14 are isotopes of carbon that differ in the number of neutrons in their nuclei, not electrons. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. The number of electrons in an atom is determined by its atomic number, which is the same for both isotopes of carbon (6 electrons).
The number of neutrons is different.
Neutrons.
They have different number of neutrons
Isotope.
Hydrogen isotopes differ by the number of neutrons they contain. Protium, the most common isotope, has no neutrons. Deuterium, another isotope, contains one neutron. Tritium, the third hydrogen isotope, contains two neutrons.

They have the same formulas but different organic structures.
Different isotopes of an element have the same number of protons but differ in the number of neutrons in their nuclei. This results in different atomic weights for each isotope. Isotopes of an element may exhibit different physical properties and may have varying degrees of stability.
Isotopes are two or more forms of the same chemical element that differ in atomic mass due to having a different number of neutrons in their nuclei. These isotopes of an element have the same number of protons and electrons but vary in their overall mass.
