Final answer:
The electron configuration for Copper (Cu) is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d⁹. The electron configuration for Silver (Ag) is [Kr]5s²4d⁹. Copper can form a Cu²+ ion by losing the 4s electron and one of the 3d electrons. Zinc has an electron configuration of [Ar]3d¹⁰4s² and can form a Zn²+ ion by losing 2 electrons.
Step-by-step explanation:
The electron configuration for Copper (Cu) is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d⁹. However, when Copper forms a Cu²+ ion, it loses the 4s electron and one of the 3d electrons, resulting in the electron configuration 1s²2s²2p⁶3s²3p⁶3d⁹.
The electron configuration for Silver (Ag) is [Kr]5s²4d⁹. However, experimental evidence has shown that the actual electron configuration is [Kr]5s¹4d¹⁰.
Zinc (Zn) has an electron configuration of [Ar]3d¹⁰4s². When it forms a Zn²+ ion, it loses 2 electrons, resulting in the electron configuration [Ar]3d¹⁰.
Copper (Cu) has an electron configuration of [Ar]3d¹⁰4s¹. When it forms a Cu+ ion, it loses one electron, resulting in the electron configuration [Ar]3d¹⁰.
