Answer:
The electronic configuration of an element is a symbolic notation of the manner in which the electrons of its atoms are distributed over different atomic orbitals.
Therefore the Aluminium electron configuration will be 1s22s22p63s23p1.
Sulfate is a polyatomic ion with 1 sulfur (6 valence electrons), 4 oxygens (4 x 6 valence electrons = 24 e-) and a charge of -2 (2 valence electrons). If we add all the electrons together we get 32 valence electrons with which to make bonds and lone pairs around the atoms in the ion.
