Why is copper considered a transition metal, although it has completely filled d-orbital (3d^10) ?

The E^@(M^(2+)//M) value for copper is positive because:

Name the oxometal anions of the first series of the transition metals in which the metal exhibits the oxidation state equal to its group number.

Explain the physical proces on the basis of which the r.m.s value of AC is defined? Derive the expression for r.m.s value of an alternating voltage. How does the value of Capacitative voltage. How does the value of Capacitative reactance of a capacitor change with the frequecny of the applied alternating e.m.f across it.
