Due to very small size,high electronegativity,high ionization enthalpy,absence of vacant d-orbital, Boron shows some anomalous properties

1-Boron is a non-metal others are metals.

2-Boron is extremely hard with high melting point.But,other elements are soft metals with low melting point.

3-Boron forms only covalent compounds.But the other elements can form covalent as well as ionic compounds.

4-The oxide of Boron is acidic.but the oxides of other elements are amphoteric or basic.

5-Hydrides of Boron are stable.

6-The trihalides of Boron cannot form dimer.
