Why electron configuration of Ag is KR 4d10 5s1 Not KR 4d9 5s2?
In 4d5 5s2, the 4d subshell is half full and the 5s subshell is full. In 4d6 5s1, the 5s subshell is half filled but the 4d subshell has no particularly stable characteristic. Barring other considerations, the most likely configuration is [Kr] 4d5 5s2.
How do you find the electron configuration?
To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals , the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
