The diagonal relationship in Be and Al is due toa)similar ionisation ...
The diagonal relationship in Be and Al is due to similar ionic size and charge/radius ratio. Generally, on moving from left to right across a period, the ionic charge increases to maximum and then decreases, while the ionic size decreases, causing an increase in its polarising power (Fajan's rule). On the other hand, on moving down a group the ionic charge remains the same white ionic size increases. Therefore, polarising power decreases. On moving diagonally, these two effects partly balance each other and therefore, there is no marked change in their properties.

Diagonal Relationship in Be and Al:
The diagonal relationship between beryllium (Be) and aluminum (Al) is primarily due to their similar ionic size and charge/radius ratio.
The other options are not as relevant in explaining the diagonal relationship between Be and Al:
In conclusion, the similar ionic size and charge/radius ratio between beryllium and aluminum are the key factors that give rise to the diagonal relationship observed in their chemical behavior.
The diagonal relationship between beryllium (Be) and aluminum (Al) is primarily due to their similar ionic size and charge/radius ratio.
- Ionic Size: Both beryllium and aluminum have comparable ionic sizes due to their similar electronic configurations. Beryllium forms a 2+ cation while aluminum forms a 3+ cation, resulting in similar ionic sizes.
- Charge/Radius Ratio: The charge/radius ratio is also similar for Be2+ and Al3+ ions, which leads to comparable chemical properties. This similarity allows for the formation of compounds with similar structures and bonding characteristics.
The other options are not as relevant in explaining the diagonal relationship between Be and Al:
- Similar Ionization Enthalpy: While beryllium and aluminum do have somewhat similar ionization enthalpies, this factor alone does not account for the observed diagonal relationship.
- Similar Metallic Character: Beryllium is a non-metal while aluminum is a metal, so their metallic characters differ. This difference in character does not contribute to the diagonal relationship between the two elements.
- Similar Electronegativity: Beryllium and aluminum have different electronegativities, with beryllium being less electronegative than aluminum. Therefore, similar electronegativity is not the driving force behind their diagonal relationship.
In conclusion, the similar ionic size and charge/radius ratio between beryllium and aluminum are the key factors that give rise to the diagonal relationship observed in their chemical behavior.
