It is easier to determine the electron configurations for the p-block elements in periods 1, 2, and 3 than to determine the electron configurations for the rest of the p-block elements in the periodic table because
they have a larger number of core electrons.
their electrons are assigned to s and p orbitals only.
their electrons are placed in a higher number of orbitals.
they have more valence electrons available for bonding.

Answer:

Their electrons are placed in a higher number of orbitals

Explanation:

  • Suppose a element be Ga .

The atomic no is 31

The configuration is given by

[tex]\\ \sf\longmapsto 1s^22s^22p^63ss^23p^63d^{10}4s^24p^1[/tex]

Or

[tex]\\ \sf\longmapsto [Ar]3d^{10}4s^24p^1[/tex]
