Question

What are isotopes?Expain with example.​

Answer 1

Answer:

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.

here is the answer my friend.

What are Isotopes?

• 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.

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 23592U and the uranium-239 isotope can be represented as 23992U.
