Describe all the similarities and differences in the structure of a Boron atom and a Boron Ion. (Mass = 11). You need to mention PEN, Electron arrangement, Charge (and why) and Stability (and why).
Atom. P=5, E=5, N=6. Arrangement 2,3. No Charge (P=E). Not stable (has incomplete valence energy level). Ion. P=5, E=2, N=6. Arrangement 2. 3+ Charge because 3 more protons (+) than electrons (-). Stable because full outer valence energy level.
