• (a) All the elements in the same column as boron have the same number of valence electrons (3).

• Hence, they all have valency equal to 3.

• (b) All the elements in the same column as fluorine have the same number of valence electrons (7).

• Hence, they all have valency equal to 1.

Answer 2

The boron shares its three electrons with three fluorine atoms. The fluorine atoms follow the octet rule, but boron has only six electrons. Although atoms with less than an octet may be stable, they will usually attempt to form a fourth bond to get eight electrons.
