Question

How can you find the electron configuration of Zn?

Answer 1

By taking the atomic number of `Zn`, and use of the old `"aufbau principle."`

Explanation:

For `Zn` we got `Z=30`....and thus....

`1s^(2)2s^(2)2s^(6)3s^(2)3s^(6)3d^(10)4s^(2)`

...and thus we have distributed 30 electrons as required.....
