Question

abnormal behavior of carbon and boron ​

Answer 1

*BORON*

1) Boron being small is harder than the other elements of its group.

2) It has higher melting and boiling point than those of the other members of its group.

3) Boron forms only covalent compounds while all other members form both ionic and covalent compounds.

*CARBON*

1) Carbon in form of diamond is very hard as compared to other members of group 14.

2) It has higher melting point and boiling point than other members of the group14.

3) Carbon has only 4 valence orbitals ,therefore ,at the maximum, it can accommodate 4 pairs of electrons around it.
