Give the electronic structure of a boron atom, one mark.

The hierarchy of the electronic structure is shown in the following table.

First of all, you have the wrong "electronic structure" for bromine.

The electronic structures of atoms can only be described in quantum terms, and are now well understood.

This is called determining the electronic structure of the molecule.

It is required that the d-bands of the electronic structure are filled.

The electronic structure is often also omitted or represented in a highly simplified way.

The electronic structure there is not perfect; instead, it's disturbed.

We also examined the electronic and nuclear structure of atoms.

This is due to the unusual electronic structure of the oxygen molecule.
