Step2: Recall electron - related facts for Oxygen

Oxygen has atomic symbol O, 8 electrons, 6 valence electrons. It gains 2 electrons to be stable and has oxidation number - 2.

Step3: Recall electron - related facts for Chlorine

Chlorine has atomic symbol Cl, 17 electrons, 7 valence electrons. It gains 1 electron to be stable and has oxidation number - 1.

Step4: Recall electron - related facts for Sodium

Sodium has atomic symbol Na, 11 electrons, 1 valence electron. It loses 1 electron to be stable and has oxidation number + 1.

Step5: Recall electron - related facts for Potassium

Potassium has atomic symbol K, 19 electrons, 1 valence electron. It loses 1 electron to be stable and has oxidation number + 1.

Step6: Recall electron - related facts for Fluorine

Fluorine has atomic symbol F, 9 electrons, 7 valence electrons. It gains 1 electron to be stable and has oxidation number - 1.

Step7: Recall electron - related facts for Nitrogen

Nitrogen has atomic symbol N, 7 electrons, 5 valence electrons. It gains 3 electrons to be stable and has oxidation number - 3.

Step8: Recall electron - related facts for Aluminum

Aluminum has atomic symbol Al, 13 electrons, 3 valence electrons. It loses 3 electrons to be stable and has oxidation number + 3.
