How does the size of an anion compare with the size of its original (electrically neutral) atom? a) the anion is larger than the original atom b) the sizes are equal c) the anion is smaller than the original atom d) anions of some atoms are larger, while others are smaller than the original atom

Remark

The anion will take on electrons. Something like Cl2 + 2e- ===> 2Cl- is an example.

If electrons are taken on, it is normally on the outside ring. That being the case the electrons have to spread out some to accommodate the additional electrons: the ion should increase in size and is larger than the parent atom.

The answer should be A.

B is wrong: they are not equal in size

C is wrong: The anion has to be larger to accommodate the  extra electrons.

D: If there are exceptions to A, I have no idea what they are. D is incorrect. I think you are intended to choose A.

the answer is   c.) 1575 j.
