Question

for the following elements show the allocation of electrons to their orbitals on the basis of the Pauli exclusion principle and Hund's rule.

a) Carbon

b) Silicon


Thanks!

Answer 1

a) Carbon
[He]2s²p²

b) Silicon
[Ne]3s²p²

Hund rule -> fill from bottom to top
Pauli -> first you fill orbitals with one spin and then the other

ex. if you have 4 electrons in p orbitals

P 11 1 1

p.s. if they don't delete this too

Answer 2

I don't understand your trouble here.
6C is 1s2 2s2 2p2. If you want boxes with electrons in them we can't draw that on this forum.
