Question
What is the electronic configuration of Chloride ion?
- 17
- 18
- 19
- 16
Hint:
The electronic configuration of chlorine iron is 2,8,8 and it has 18 electrons.
The correct answer is: 18
- The atomic number of the chlorine element is 17.
- The electronic configuration is the distribution of electrons in the shells and the electronic configuration of chlorine is 2,8,7.
- As the chloride gains an electron, its electronic configuration is 2,8,8 and the total electrons are 18.
