The electron configuration of Al (2,8,3) the valency of Al is 3, the total valency = 1*3 = 3 . The electronic configuration of O (2,6) The valency of O is 2 ,The total valency of O for O2 is 2*2=4 , The total valency of Al in Al2O3 = 2*3= 6, The total valency of O in Al2O3 = 3*2= 6
@@MuradMahamed-tv3vci don’t get why oxygen has only 2 valence electrons. it belongs to the group 16 so it has 6 v. electrons. i think the video means, oxidation number because oxygen has -2 oxidation number. although the difference is that its positive not negative

Valency and oxidation number is different. Balancing chemical reaction using LCM method uses the total valency , valance electron and valency is similar for metals but for nonmetal valency = 8 -valence electron ,For example , Al is metal valence electron is 3 , the valency of Al also 3, O is non metal , the valance electron of O is 6, Valency of O = 8-6 = 2
Its a really nice video. I couldn't find much videos related to the lcm method of balancing .Thank You for clearing my doubts.
It would be better if the audio is loud andd clear.
Keep it
wonderful
sorry i did not fully understand where did the 3, 4, 6, 6 came from in the step 2. pls help me
3 is group of aluminium or valance elecetron of almunium and 4 is 2 as valance electron of oxygen timus 2 as molecule is 4
