Consider the information you have about the element chlorine in question #1. Based on that knowledge, what do you know about the atomic structure of aluminum? All BUT ONE statement is true. A)
Aluminum has 13 neutrons.

B)
Aluminum has an atomic number of 13

C)
Aluminum has 13 protons+ in the nucleus.

D)
The number of protons equals the number of electrons.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
