🤓 Based on our data, we think this question is relevant for Professor Yousif's class at University of Detroit Mercy.

**Atomic number = # of protons = # of electrons**

Ag: atomic number = 47 → 47 protons & **47 electrons**

**Neutral Ag: ****1s ^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{2}4d^{9}**

*d orbitals → prefer to be half-filled or fully filled*

*move 1 electron from 5s to 4d*

**Neutral Ag: ****1s ^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{1}4d^{10}**

**Neutral Ag: ****1s ^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}5s^{1}4d^{10}**

• Shorten the electron configuration by including a noble gas:

**[ 1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{6}]6s^{2}**

Is the electron configuration for Ag^{+} [Kr]4d^{10}?
