(a) What property do all elements in the same column of the Periodic Table as boron have in common?
(b) What property do all elements in the same column of the Periodic Table as fluorine have in common?

(a) All elements in the same column of the periodic table as boron have the same valency that is their valency will be 3.

(b) All the elements in the same group of the periodic table as fluorine are known as halogens. Halogens are placed in group 17 and have seven valence electrons. Therefore, all of them will have their valency 1.


[Extra information: 

Periodic table: A periodic table is a tabular display of all the chemical elements that are arranged by the order of their atomic number, electronic configuration, and recurring chemical properties. 

It displays the names, atomic numbers, symbols and atomic weights of known elements. It serves as a great tool for solving chemistry problems.


A periodic table is divided into groups (columns), where elements with each group behave similarly while bonding with other elements; and periods (rows), where elements in one period have the same number of electron shells.

The periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one reference. The table can be used to predict the properties of all the elements, even those that have not yet been discovered.]
