Question
1. How the size of cations and anions compares to the size of their neutral atoms and explain why2. Define the term isoelectronic (same # electrons) and how the sizes of isoelectronic atoms compare
3. Define the Octet and Duet rule and how it explains the charges on common ions and both
covalent and ionic bonding (for representative elements only)
Explanation / Answer
In terms of size: Cations > Neutral atom > Anions because of crowding of electrons subsequent repulsion. In isoelectronic atoms, the atom with larger atomic number has greater size dude to extra attraction from the nucleus.
