Just like lithium and beryllium in Groups Land 2, boron also shows anomalous behaviour. In general, the boron chemistry resembles that of silicon (occupying a diagonal position in the periodic table) more closely than that of Al, Ga, In and TI. This is because of the small size and high electronegativity of boron as compared to those of Al, Ga, In and TI. Boron resembles silicon and differs from Al, Ga, In and TI in the following manner:
