Which of the following elements is going to be the most reactive and why? Nitrogen or Oxygen? A) Nitrogen because it has the strongest attractive force and the largest
electronegativity.
B) Oxygen because it has the weakest attractive force and the largest
electronegativity.
C) Oxygen because it has the strongest attractive force and the largest
electronegativity
D) Nitrogen because it has the weakest attractive force and the largest
electronegativity.

(C) Oxygen because it has the strongest attractive force and the largest

electronegativity

Explanation:

Oxygen will be most reactive

configuration =

As oxygen need only two electrons to complete its octet.

Oxygen will have stronger force than nitrogen as it will tend to pull electrons more to complete its octet. Also along the period electronegativity increases so oxygen has higher electronegativity than nitrogen

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
