Question

Predict the electron configuration exception for gold (Au) based on the behavior of copper and silver.

Accepted Answer

Gold will promote an electron from the 6s orbital to the 5d orbital, resulting in $$6s^{1}$$ $$5d^{10}.$$

Answer

Gold will promote an electron from the 6p orbital to the 5d orbital, resulting in $$6s^{2}$$ $$5d^{10}.$$

Answer

Gold will not promote any electrons, resulting in $$6s^{2}$$ $$5d^{9}.$$

Answer

Gold will promote an electron from the 5d orbital to the 6s orbital, resulting in $$6s^{2}$$ $$5d^{9}.$$
