The ease to remove an electron from an element is also related to cell potential.

Larger (↑) E° stronger oxidizing agent


Gather the reduction potentials.

Sn2+(aq) + 2e→ Sn(s)           Ered =  -0.14V

Cl2(g) + 2e- → 2 Cl-(aq)          Ered =  1.36 V

Ag+(aq) + e- → Ag(s)               Ered =  0.80 V

Cu2+(aq) + e- → Cu(s)             Ered = 0.34 V

K+(aq) + e- → K(s)                    Ered = -2.92 V
