Answer

First: 47 protons, 47 electrons, 60 neutrons Second: 47 protons, 47 electrons, 62 neutrons

Work Step by Step

From the periodic table, for silver (Ag) $Z=47$: For both isotopes $Z=p^+=e^-=47$ For the first $A=Z+n=107\rightarrow n = 60$ 47 protons, 47 electrons, 60 neutrons For the second $A=Z+n=109\rightarrow n = 62$ 47 protons, 47 electrons, 62 neutrons
