Anomalous behaviour of beryllium
- Anomalous behaviour of an element refers to the deviation of the properties and behaviour of an element from its usual or normal behaviour.
- Beryllium has small atomic and ionic size.
- The high ionization enthalpy andsmall size of alkaline earth metals results in the formation of covalent compounds that are easy to hydrolyze.
- The coordination number of beryllium is not greater than 4 due to the presence of four electrons in the valence shell.
- The oxide and hydroxide of beryllium are amphoteric in nature.
