1. Silver nitrate – Silver nitrate is an inorganic compound with chemical formula AgNO3. This compound is a precursor to many other silver compounds. It is far less sensitive to light than the halides and it was once called lunar caustic because silver was called luna by the ancient alchemists, who believed that silver was associated with the moon.
The silver atom has 5 electron orbits (energy levels) with a total of 47 electrons. Beginning with the orbit closest to the nucleus and working outward, the number of electrons per orbit should be: 2, 8, 18, 18, 1. Of course, the nucleus contains 47 protons and 61 neutrons.
