what are isotopes?Explain giving one example?
Answers
Explanation:
The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.
what is isotope?
➡️ 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.
