Na + O2 > Na2O (addition of oxygen)
Fe + Cl3 > FeCl3 (Addition of electronegative)
★★Oxidation is an exothermic reaction
I HOPE IT WILL HELP YOU☺️✌️
Oxidation is a chemical reaction involving the addition of oxygen.
Ex:metals such as sodium and potassium spontaneously react with oxygen to form their respective oxides.It is an exothermic reaction
Oxidation reaction may be endothermic or exothermic depend upon the nature of reactant. Those oxidation reaction in which reactant are highly reactive give exothermic reaction. Exothermic: combustion of hydrocarbons, thermite rxn, burning a reactive metal for example sodium in air.
Redox is a chemical reaction in which the oxidation states of atoms are changed. Any such reaction involves both a reduction process and a complementary oxidation process, two key concepts involved with electron transfer processes.
● as al has very ionization energy and for cl its not easy to withdraw 3 electrons from al’s outer most shell because cl is not enough electronegative
therefore, al rather loosing 3 electrons it shares its electrons with 3 cl ions and when electrons shared with 2 atoms ; covalent bond is formed
i hope will you
