for an isotope of ag with mass number 108, the number of protons and neutrons, are:

1. 61 protons, 47 neutrons
2. 47 protons, 61 neutrons
3. 54 protons, 54 neutrons
4. 108 protons, zero neutrons

Explanation:

Step1: Find atomic number of Ag

Silver (Ag) has an atomic number of 47, so protons = 47.

Step2: Calculate neutrons

Mass number = protons + neutrons. So neutrons = 108 - 47 = 61.

Answer:

1. 47 protons, 61 neutrons
