Question

element which so highest negative standard electrode potential​

Answer 1

Answer:

Negative electrode potential means the metal electrode is donating electron(s) to another electrode. In other words it is under oxidation process and is reducing the other electrode. ... So zinc is a reducing electrode. It works as anode (negative) in electrochemical cell.

Explanation:

Element (Li) having bottom-most position has lowest reduction potential hence it is the strongest reducing agent. e.g. The element like Zn, Cd, Ni, K etc. are good reducing agents.
