iodine
aluminum
carbon
nitrogen

Answer 1

Aluminium

Step-by-step explanation:

Because it does

Answer 2

Answer: Aluminium has fewest valence electrons available for bonding.

Step-by-step explanation:

Valence electrons are the total number of electrons present in last shell or in valence shell of an atom.

Electronic configuration of given elements are:

1) Iodine

`[I]^(53)=[Kr]4d^(10)5s^25P^5`

7 valence electrons available for bonding.

2) Aluminium

`[Al]^(13)=[Ne]3s^23P^1`

3 valence electrons available for bonding.

3) Carbon

`[C]^(6)=[He]2s^22P^2`

4 valence electrons available for bonding.

4) Nitrogen

`[N]^(7)=[He]2s^22P^3`

5 valence electrons available for bonding.

From the electronic configurations of given elements we can see that aluminium has fewest valence electrons available fro bonding.
