Question

what are isotopes ? give full explanation as possible

Answer 1

Hey, my friend here is your answer, hope it helped

Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

what is isotope?

$\huge\bf{\underline\pink{Answer}}$

$\huge\bf{\underline\orange{Isotopes}}$

➡️ Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties.

Property:-

➡️ Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

Isotopes Examples:-

➡️ Carbon-14 => A naturally occurring radioactive isotope of carbon having six protons and eight neutrons in the nucleus.

➡️ Iodine-131 => It is an isotope because it contains a different number of neutrons from the element iodine.

➡️ All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial isotopes are unstable and therefore radioactive.
