Expert Answer
The following points illustrate the anomalous behavior of Be and its resemblance with Al.
(i) Unlike groups - 2 elements but like aluminium, beryllium forms covalent compounds.
(ii) The hydroxides of Be, [Be(OH)2] and aluminium [Al(OH)3] are amphoteric in nature, whereas those of other elements of group - 2 are basic in nature.
(iii) The oxides of both Be and Al i.e. BeO and Al2O3 are high melting insoluble solids.
