diagonal relationship btw aluminium and Sl
Dear Student,
The diagonal relationship exists between
DIAGONAL RELATIONSHIP BETWEEN Be AND Al
The diagonal relationship exists between
- Beryllium and aluminium
- Between Boron and Silicon
DIAGONAL RELATIONSHIP BETWEEN Be AND Al
-
Be2+ and Al3+ have almost same and smaller size and thus favour for covalent bonding. Both these form covalent compounds having low melting point and soluble in organic solvent.
-
The standard oxidation potential of both the metals are same (Be2+=1.69 volts, Al3+=1.70 volts).
-
Both metals become passive to the attack of acids
- The oxides of metals (BeO ,Al2O3) are amphoteric in nature
- Both metals form stable complexes (BeF3- , AlH4-)
- Both are non- metals and exist in allotropic forms.
- Both have high mp and are semiconductor
- Both B and SI form volatile hydrides like boranes and silanes
- Both form only covalent compounds
- The chlorides of both boron and silicon are easily hydrolyzed by water
