Toexplain: the reason the oxidation numbers of nitrogen and fluorine differ.
Explanation of Solution
Introduction:
The total number of electrons that an atom either receives or loses in order to form a
The oxidation number of an element gives information about the charge that a particular element carries. The oxidation number of all the elements in a period differs.
Fluorine and nitrogen both belong to the period of 2 but different groups. Fluorine belongs to group 17 and nitrogen belongs to group 15. The atomic number of nitrogen is 7 and the electronic configuration of nitrogen is 2.5. Thus, it needs 3 electrons to complete its outermost shell and it gains 3 electrons and it will show an oxidation number of 3-.
Similarly, the atomic number of fluorine is 9. Its electronic configuration is 2.7. Thus, it requires one electron to get noble gas configuration, and hence, it gains 1 electron and shows an oxidation number of 1-.
Conclusion:
Hence, the oxidation numbers of fluorine and nitrogen are 1- and 3- respectively as both belong to a different group. On moving left to right, this number decreases and this is why it differs for both the atoms.
