Question

compare the atomic sizes of chlorine atom cl and chlorid ion cl-​

Answer 1

Answer:

Atomic Size Is directly proportional to Negative Charge

Cl- > Cl

Atomic Size Inversely proportional to Positive Charge

Anion always Greater than its atom

Cation always less than its atom

Answer 2

Answer:

The only difference between an atom and its ions is the number of electrons that surround the nucleus. Example: A neutral chlorine atom contains 17 electrons, while a Cl- ion contains 18 electrons. ... For the same reason, positive ions should be smaller than the atoms from which they are formed.
