Question
Chapter 27, Problem 1QAP
To determine
The definition of an isotope.
Expert Solution & Answer
Explanation of Solution
As the atoms of its each element has its unique number of protons and the same number of electrons. Many of the properties of atoms are related to this number usually known as atomic number Z, as well many properties of nuclei arise from both the value of Z and the value of the neutron number N, which is known as number of neutrons in the nucleus. For each element the most common configuration of N and Z corresponds to the most nuclide, nuclei of that element with a different number of neutrons is known as isotopes.
So, Isotopes are nuclides with the same atomic number, Z, but a different number of neutrons, N.
