Question

10. What is the correct electron configuration for Au?

Answer 1

Answer:

$^{79}Au=1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^24d^{10}5p^66s^24f^{14}5d^9$

Explanation:

Here, we want to get the correct electronic configuration for Au

The element gold has 79 electrons

We have the configuration as follows:

$^{79}Au=1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^24d^{10}5p^66s^24f^{14}5d^9$
