I believe it would be better to use an orbital designation than the written configuration, if the number of electrons in the ground state of the atom are quite high for the given element, as above 50, for instance.
This saves space and also one can see the discrete quantized energy levels associated with the subshells of the main energy levels if written in orbital designation.
Answer:
2Cl+2e -->2Cl^-
Explanation:
reduction is the gain of electrons and this is the only option which fits the definition.
I am very sure that the answer is C. Hope it’s right :)
