List of elements based on hydrogen scale is called________________?
Correct answer: D. electrochemical series
- A. periodic table
- B. groups
- C. periods
- D. electrochemical series
Explanation
The electrochemical series arranges elements or ions according to their standard electrode potentials, measured relative to the standard hydrogen electrode. The periodic table instead arranges elements mainly by atomic number and electronic structure. The likely wrong choice is periodic table, which is a general classification rather than a potential-based list.

About Redox Reactions
Redox reactions involve oxidation and reduction occurring together, with electrons transferred between species or oxidation numbers changing. The topic covers assigning oxidation states, identifying oxidizing and reducing agents, balancing redox equations by oxidation number or half-reaction methods, and connecting chemical changes with galvanic and electrolytic cells.
