We construct the Capelli elements Ck(u) = C(1k)(u) (k = 1, . . . , n) with a parameter u for the symplectic Lie algebras and orthogonal Lie algebras. They correspond to factorial Schur functions with parameter u attached to the column partitions (1k). We also give explicit formulas for Ck(u) arising from the expansion of Cn(u) = C(1n)(u) with respect to the parameter u. We use the Jacobi-Trudi formula for the factorial Schur functions Rλ(x; u) to construct the higher Capelli elements Cλ(u). They are expressed as determinants of matrices whose entries are Capelli elements Ck(u) attached to the column partitions.
