Question
To attain stability, chlorine has to gain how many electrons?
- 1
- 2
- 3
- 4
Hint:
The chlorine gains a single electron to attain its stable electronic configuration.
The correct answer is: 1
- According to the octet rule, the atoms or elements gain or lose electrons to attain a stable electron configuration.
- The outermost shell of chlorine has 7 electrons of which 1 will be unpaired.
- To become stable, the chlorine will gain one electron and make the electrons paired.
