Hi, today we will learn about Diagonal Relationship-Definition, Example, Question in this article. It is one of the important topics in chemistry where you need to understand the concept.

What is Diagonal Relationship?

some elements of the second period of the periodic table show diagonal similarity with the elements of the third period. this relation is called diagonal relationship.

Diagonal Relationship in Periodic Table

Period	Group 1	Group 2	Group 13	Group 14
2	Li	Be	B	C
3	Na	Mg	Al	Si

In the periodic table, the similarity of the two elements is observed diagonally. See the periodic table as given above.

Among the lighter members of the second and third-period components, the diagonal relationship is prominent. Thus, Li (Lithium) of Group IA shows the diagonal – the relationship with Mg (Magnesium) of Group IIA, Be (Beryllium) of Group IIA shows the diagonal – the relationship with Al (Aluminium) of Group IIIA, and B (Boron) of Group IIIA shows the diagonal – the relationship with Si (Silicon) of Group IIA.

What is the reason for diagonal relationship Or why diagonal relationship occurs?

Many of the elements in the periodic table, their chemical properties that vary with the size of the atom. As we moving across the group and period the size changes. Those atoms show diagonal relationship almost the same size.

The diagonal relationship is shown by the elements upto how many groups only?

Diagonal Relationship is shown only up to the Carbon Group. Nitrogen does not show diagonal relationship with Sulfur because it is not at all similar to Sulfur
