Question
What is the electronic configuration of Chloride ion?
- 17
- 18
- 19
- 16
Hint:
The electronic configuration of chloride is 2,8,8.
The correct answer is: 18
- The atomic number of chlorine element is 17
- The electronic configuration of chlorine is 2,8,7
- It forms chloride by gaining one electron and the atomic number of chloride is 18.
- So the electronic configuration of chloride becomes 2,8,8.
