When the lanthanum metal undergoes oxidation, it commonly forms La3+ ions. The ease of oxidation of lanthanum was studied and the following data were gathered:
I) Zinc metal deposited on the strip when a strip of lanthanum metal was immersed in an aqueous solution of Zn(NO3)2.
II) Lanthanum metal deposited on the strip when a strip of sodium metal was in an aqueous solution of La(NO3)3.
Based on this information, determine which elements best define the lanthanum's position in the activity series?
