Question

Which element has the fewest valence electrons available for bonding?

Answer 1

Answer:

Aluminium

Explanation:

Because it does

Answer 2

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

$[I]^{53}=[Kr]4d^{10}5s^25P^5$

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.
