Silver is a transition metal. You can find silver in group 11 in the periodic table. To indetify the atom is easy you just need the protons. So therefore silver atomic number is 47 because, it contains 47 electrons ( elctrons electric charge is negative), 47 protons (protons charge is positive), and 60 neutrons (neutral). It's atomic mass is 107.87.

Nitrogen is part of the group that gains electrons, its located in 5A in the periodic table. Now a to identify the atom is just looking at how much subatomic particles that atom has in the nucleus, in this case nitrogen has 14, so nitrogens atomic number is 14. This atoms nucleus holds 7 protons and 7 neutrons. Nitrogen atomic mass is 14.007. It contains 2 subatomic particles in the first shell. And the outer shell contains 5. There are two types of electric charges, 1 : protons (positive) 2 : electrons (negative).
