검증된 단계별 안내1
Identify the atomic number of cadmium (Cd), which is 48. This tells us that a neutral cadmium atom has 48 electrons.
Understand that when cadmium forms an ion, it typically loses electrons to achieve a stable electron configuration.
Recognize that the most common ion of cadmium is Cd²⁺, which means it has lost 2 electrons.
Subtract the 2 electrons lost from the neutral cadmium atom's 48 electrons: 48 - 2.
Conclude that the cadmium ion (Cd²⁺) possesses 46 electrons.
