The electron structures of boron and aluminum are similar because they share the same group, therefore they have the same amount of valence electron.

Answer:

- Both of their valence electrons are at p subshell.

- They have the first subshell full of electrons.

- Both of them have just 1 electron at the last p subshell.

Step-by-step explanation:

Hello,

In this case, we could understand their electron structures by identifying their electron configurations as shown below:


B^5\rightarrow 1s^2,2s^2,2p^1\\Al^(13)\rightarrow 1s^2,2s^2,2p^6,3s^2,3p^1

In such a way, we could notice the following similarities:

- Both of their valence electrons are at p subshell.

- They have the first subshell full of electrons.

- Both of them have just 1 electron at the last p subshell.

Best regards.
