Which of the following elements has the same oxidation number in all of its known compounds?
Correct answer: A. Beryllium
- A. Beryllium
- B. Chlorine
- C. Nitrogen
- D. Bromine
Explanation
In periodic table groups I-A, II-A members and fluorine show only one oxidation state in all of their compounds. Group I-A members show +1, Group II-A members show +2 and fluorine shows -1 in all known compounds.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
