Answer :-
[tex]\rightarrow[/tex] Due to small size and similar charge/mass ratio,boron differs from other group 13 members, but it resembles closely with silicon , the second elements of group 14 to exhibit diagonals relationship, Some important similarities between boron and silicon are given below ;
[tex]\star[/tex] Both boron and silicon are typically non metals , having high melting point, and boiling point with nearly same densities low atomic volumes and a bad conductor of current . However both are semiconductor.
[tex]\star[/tex] Both of them do not form cation and form only covalent compounds.
[tex]\star[/tex] Both exists in amorphous and crystalline state and exhibit allotropy.

The diagonal relationship between Boron and Silicon shows Anamolous behaviour in its group because of its small size and non availability of D oribital it resembles as silicon the second member of the next higher group.

Answer:
Because crossing and descending the periodic table have opposing effects, there is a diagonal relationship. It is primarily owing to the polarising power of ions.
Explanation:
In the 2nd and 3rd periods of the periodic table (the first[tex]20[/tex]elements), a diagonal relationship is believed to exist between certain pairs of diagonally adjacent elements.
- Because crossing and descending the periodic table have opposite effects, a diagonal relationship emerges. When crossing a period of the periodic table, the size of the atoms decreases, and when descending a group, the size of the atoms grows.
- Similarly, as the period progresses, the elements get more covalent, less reducing, and more electronegative, but as the group progresses, the elements become more ionic, basic, and less electronegative.
- As a result, the changes balance out whether descending a group or crossing by one element, and elements with identical characteristics and chemistry are frequently identified.
- Silicon and boron are both semiconductors. They produce acidic oxides when they are hydrolyzed in water.
