Question

The simple definition of isotopes in cemistry? !() cxd iikh ecc !() jôííñ and What are the isotonic elements in terms of simple chemistry?​

Answer 1

Answer: An isotope is 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 behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

Explanation: Two nuclides are isotones if they have the same neutron number N, but different proton number Z. ... Similarly, 36S, 37Cl, 38Ar, 39K, and 40Ca nuclei are all isotones of 20 because they all contain 20 neutrons. They are called isotonic elements.
