Answer: Aluminium has fewest valence electrons available for bonding.
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
[tex][I]^{53}=[Kr]4d^{10}5s^25P^5[/tex]
7 valence electrons available for bonding.
2) Aluminium
[tex][Al]^{13}=[Ne]3s^23P^1[/tex]
3 valence electrons available for bonding.
3) Carbon
[tex][C]^{6}=[He]2s^22P^2[/tex]
4 valence electrons available for bonding.
4) Nitrogen
[tex][N]^{7}=[He]2s^22P^3[/tex]
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.
