Why the elements of group 13 are called p-block elements?

1.	Why the elements of group 13 are called p-block elements?
Answer» Group 13 elements are called p-block elements because the last electron is present in the p-orbital (np₁). The valence shell configurations are B (2s² 2p¹), Al (3s², 3p¹),Ca (4s², 4p¹), In (5s²5p¹) Tl (6s² 6p¹)
