How do I find the number of electrons in an Isotope? For example, I know that in the image attached the isotope has 45 protons and 58 neutrons, but I am unsure as to how to find the number of electrons in the isotope.

Answer:
The answer to your question is: 45 electrons
Explanation:
Isotopes are molecules that have the same number of protons but the number of neutrons is different.
Also, in a neutral atom, the number of protons and electrons is the same.
In the example given, we can see that the atom is neutral so, the number of protons = 45 and the number of electrons = 45.
