Number of shells represent the period.
Number of valence electrons represent groups.

Answer 2

the electronic configuration relates to the periodic table in the form of blocks. say for example, s block, p block or d and f block. We write the periodic position of the atom while writing its electronic configuration.

Say for example, for HYDROGEN, THE ELECTRONIC CONFIGURATION IS, 1S1
