About Blocks of the Periodic Table
Electron configurations divide elements into s, p, d and f blocks according to the subshell receiving the last electron. Work includes the positions, valence-shell configurations and general properties of s-block and p-block elements, along with periodic trends in atomic size, ionisation energy, electron affinity and electronegativity.
