검증된 단계별 안내1
Identify the element with atomic number 47. Use the periodic table to find that the element is Silver (Ag).
Understand that elements tend to form ions by gaining or losing electrons to achieve a stable electron configuration, often resembling the nearest noble gas.
Silver (Ag) is in Group 11 of the periodic table, which typically forms a +1 charge when it loses one electron.
Consider the electron configuration of Silver: [Kr]4d^10 5s^1. Losing one electron from the 5s orbital results in a stable configuration.
Conclude that Silver commonly forms a +1 charge as it loses one electron to achieve a more stable electron configuration.
