Renditja e joneve sipas rritjes së rrezes jonike është:

\[ \text{Al}\ (Z = 13),\quad \text{O}\ (Z = 8),\quad \text{N}\ (Z = 7),\quad \text{Mg}\ (Z = 12) \]

A) $\text{Al}^{3+},\ \text{O}^{2-},\ \text{N}^{3-},\ \text{Mg}^{2+}$

B) $\text{Al}^{3+},\ \text{Mg}^{2+},\ \text{O}^{2-},\ \text{N}^{3-}$

C) $\text{Mg}^{2+},\ \text{O}^{2-},\ \text{N}^{3-},\ \text{Al}^{3+}$

D) $\text{O}^{2-},\ \text{N}^{3-},\ \text{Mg}^{2+},\ \text{Al}^{3+}$

Numri i elektroneve për secilin jon

Për të krahasuar rrezen jonike, fillimisht përcaktojmë sa elektrone ka secili jon.

Për jonet pozitive, elektronet hiqen:

\[ \text{Al}^{3+}:\quad e^- = 13 - 3 = 10 \]

\[ \text{Mg}^{2+}:\quad e^- = 12 - 2 = 10 \]

Për jonet negative, elektronet shtohen:

\[ \text{O}^{2-}:\quad e^- = 8 + 2 = 10 \]

\[ \text{N}^{3-}:\quad e^- =…
