    Zinc’s ground state electronic configuration is 3d104s2. As such, it can readily form complexes with an oxidation state of +2. However, higher oxidation states are unknown as they would imply that electrons from the highly stable filled 3d orbitals be involved in bonding. zn+ have d9 configuration while d10 configuration is most stable so very high amount of IP needed so it exists only on +2 oxidation state

    plz explain 7 point

    eduncle-logo-app

    can you send me which topic is it?

    eduncle-logo-app

    why other elemants donot form +1

    eduncle-logo-app

    Cu have EC of 3d104s1 so it removes 1e to get d10 which is highly stable configuration so it exists in +1 oxidation state

    this topic.

    eduncle-logo-app

    while other elements can show many oxidation state +1 to +7

    eduncle-logo-app

    ..

    eduncle-logo-app

    no sir

    eduncle-logo-app

    other elemants 1 show ni krte

    eduncle-logo-app

    Ag+1 show krta he

    eduncle-logo-app

    ......

    eduncle-logo-app

    3 d ki baat kr ri hub

    eduncle-logo-app

    iska bhi reason stability hi Hoga sir

    eduncle-logo-app

    yes, depends krta he electronic configuration pr

    eduncle-logo-app

    other compounds+1 pr stable nhi hote

    eduncle-logo-app

    ok

    eduncle-logo-app

    sbka ik hi reason hota haina sir

    eduncle-logo-app

    yes

    eduncle-logo-app

    Shweta is table ko check kro yha Cu or Cr k alava sbhi me 4s2 configuration aa rha he to 1 e niklte hi 4S1 aayega or configuration unstable ho jayega na

    eduncle-logo-app

    fully filled half filled se jada stable hota he na

    eduncle-logo-app

    okokok

    eduncle-logo-app

    ok

    d9 configuration

    eduncle-logo-app

    3d10 4s0 configuration give Zn extra stability rather than a 3d9 4s0

    eduncle-logo-app

    got this shweta?

    eduncle-logo-app

    yes sir

    eduncle-logo-app

    fully filled configuration hai most stable honge na

    eduncle-logo-app

    yes sir aa gya samagh
