Period, group and block from Z

You will fill the subshells in the Aufbau order and read where an element sits in the long form, for atomic numbers up to 54.

The idea. The period is the highest shell with electrons. The block is the last subshell filled. The group: the s electrons in the s-block (helium is 18), $12$ + p electrons in the p-block, d + outer s electrons in the d-block.

Your tasks.

1. In configuration, return a dictionary of each filled subshell and its electrons.
2. In place, set the period and the block.
3. In place, set the group.
