Consider the elements F,Cl,O & N . What is the correct increasing order of their chemical reactivity in terms of the oxidizing property

The oxidising character of elements increases from left to right across a period  Thus we get the decreasing order of oxidising property as F>O>N.
 The oxidising property of  elements decreases down a group so we get F>Cl.Also the oxidising character of oxygen is more than that of chlorine .That is O>Cl.So we get F>O>Cl>N.
