Valency mean what it can get or loose to get octet. For oxygen it's 2 and for chlorine 1 just like that

Here is a simple thing which can help. but it does not guarantee correct . But can help most of the time . If you have a compound like NO3 - . First put the valence electrons of the center atom then the charge . and the add the valency of the ligands one by one . if it exceeds 8 then there may...

Thank you

I can't understand because work is a scaler quantity and how can it be a net. I mean resultant. Only vector have resultant. 1/2m(v2-u2 ) =f*s. This is the work energy theorem. Then how it will work for problems involving elastic potential energy. Please explain me and clear my doubts

You are saying that the work energy theorem states the Change in kinetic energy equals work done on the object. But that is an over simplification of the work energy principle which can only applied to horizontal motion. But the real work energy principle is. The change in mechanical energy of...
