Electrodeposits of nickel result in beautiful, silvery nodules.  Nickel is also found in NiCd batteries.  The following reactions take place in...

Atomic # = 28 Atomic weight = 58.693

Electrodeposits of nickel result in beautiful, silvery nodules.  Nickel is also found in NiCd batteries.  The following reactions take place in these batteries:

Cd(s) + 2 OH–(aq) →Cd(OH)2(s) + 2 e–                                                                     (negative electrode)

2 NiOOH(s) + 2 H2O(l) + 2 e–>→2 Ni(OH)2(s) + 2 OH–(aq)                   (positive electrode)
