Question

The electronic configuration of chloride ion is the same as that of an argon atom. What is the difference between the two​

Answer 1

Answer:

The electronic configuration of chloride ion is same of the argon electronic configuration.As the chloride ion cl^- gains 1 electron to attain the stability. ∴HENCE,we can say chloride ion as a argon ato.

Answer 2

Explanation:

It has an electron configuration of 2 electrons in the first energy level, 8 in the second, and 7 in the third, for a total of 17 electrons. But the third energy level can hold up to 8 electrons. So when chlorine gets one more electron to fill that third level, it becomes a chloride ion with a net charge of -1.
