Cause of variable valency | Why Fe and Cu have two valency ?

[@kiranturyaan98]

Thanks sir ..... your concept is most understandble

[@NikhilKumar-sf4oq]

I like your teaching sir ❤

[@HamidIjaz-yh9mw]

Well done sir

[@ghanapandey623]

SIR.... GREAT... FANTASTIC EXPLANATION

[@wrestlewithmagic123]

There's no need of background music...

[@krishnaprasadgupta1673]

Acha samajhaya sir . Samjh aa gaya

[@kritigarg8192]

Thanku sir meri problem slove ho gai

[@anilkumarsharma8901]

Cu copper wire mein kitna current kitna garmi paida kar shakta hai???

[@sohammane8338]

Sir aap toh bahut aache teacher ho i am in 7th standard and i was confused about valency but when i get to know that The octate is applicable for the first 20 elements only,my doubts get cleared👍👍😊

[@sohammane8338]

But what’s the connection between chemistry and movies? Why would i watch movies to learn chemistry??

[@senorita6375]

Sir copper ka vallency 1 and 2 hota hai to chemical formula banate samay humhen kaun sa valency ka copper Lena hai please sir answer my question

[@SKOOLmateeLEARNING]

CU 2+ MAXIMUM TIME

[@senorita6375]

@@SKOOLmateeLEARNING maximum time Kya hai

[@trykarle8322]

Sir i learned about k, l, m orbit.... When the s/p/d orbit will use??

[@y.yogita7046]

Sir may I know why have you put 5 blocks for 3d6

[@SKOOLmateeLEARNING]

D orbital has ten electron capacity and every block capacity is 2 electron.

[@y.yogita7046]

@@SKOOLmateeLEARNING Thank you sir

[@anilkumarsharma8901]

Cupertino Cupric ????

[@bhanuchole765]

Sir cobalt ka valency thodasa confuse hein

[@Poonamdevi-vr9gg]

I m confused in fe case that why 4s orbital shell donate electron which is stable can anyone will tell me pls

[@SKOOLmateeLEARNING]

Because that one is outermost orbit and outermost orbit transfer electron for stability.

[@kidmovie1561]

Sir Zn ka valency laiye please

[@darkstromx1465]

Then why magnese has variable velency although its 4s is full filled and 3d is half filled ? I mean it is stable then its valency should be only 2 because of 4s2 .

[@harrysimplyharry]

Bhai..copper is 29 so 2,8,18 honi chaiye last mein 1 elements bacha

[@Sameer_3101]

Calcium ka 20 hai to last me S orbit me 2 electron hai to phir pair ban gya to wo stable kyu nhi hai?

[@as83singh]

Sir why will fe transfer from s shell in variable valency

[@SKOOLmateeLEARNING]

For stability.

[@amoux8715]

Thanks sir

[@dipaksharma2990]

Sorry sir but all transition element don't have variable valency, zinc has only one valency as its only one shell is incomplete

[@manoharpaunikar3125]

Sir aap thode aur examples leke samjhaon na please

[@VikramSingh-ff1yt]

Thanks

[@MrPankaj190]

Cu ka 4s1,3d10 hota he

[@narendrayadav7251]

Thanku sir

[@Sameer_3101]

Fe ka 4S2 wala to stable hai phir wo kyu deta hai electron?

[@SKOOLmateeLEARNING]

Kyu ki wo last orbit ka electron hai..
