define isotopes with example
please help me
Answers
Answer:
Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. In other words, isotopes are variants of elements that differ in their nucleon numbers due to a difference in the total number of neutrons in their respective nuclei. For example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon. Carbon-14 contains a total of 8 neutrons, carbon-13 contains a total of 7 neutrons, and carbon-12 contains a total of 6 neutrons.
Explanation:
examples - 1.)Carbon-14. A naturally occurring radioactive isotope of carbon
having six protons and eight neutrons in the nucleus. ...
2.) Iodine-131. It is an isotope because it contains a different number
of neutrons from the element iodine.

Isotopes are primarily represented in two different ways:
By writing the name of the element followed by a hyphen and the mass number of the isotope. For example, uranium-235 and uranium-239 are two different isotopes of the element uranium.
By following the AZE notation (also known as the standard notation). This involves writing the symbol of an element and prefixing the atomic number in subscript and the mass number in superscript. For example, the uranium-235 isotope can be represented as ²³⁹U⁹² and the uranium-239 isotope can be represented as ²³⁹U.⁹²
