Understanding Isotopes: Atoms with the Same Number of Protons but Different Neutrons

Izote (also known as isotope) is a term used in chemistry and physics to describe atoms of the same element that have the same number of protons in their atomic nuclei but differ in the number of neutrons. Neutrons are subatomic particles that have no electric charge and reside within the nucleus of an atom, along with protons.

Isotopes of a given element have the same chemical properties but may differ in their physical properties, such as mass, melting point, and radioactivity. For example, carbon-12 and carbon-14 are two isotopes of the element carbon. Both isotopes have six protons in their atomic nuclei, which makes them both carbon atoms, but carbon-14 has eight neutrons, while carbon-12 has six neutrons.

Isotopes can be used in a variety of applications, such as dating rocks and minerals, studying chemical reactions, and identifying the source of a substance. For example, carbon-14 is often used to date organic materials that are up to about 50,000 years old, as it decays at a predictable rate. Similarly, uranium-238 and uranium-235 are two isotopes of the element uranium that have different numbers of neutrons and differ in their radioactive properties.

Overall, isotopes are atoms of the same element that have the same number of protons but differ in the number of neutrons in their atomic nuclei, and they can be used in a variety of scientific applications.
