EasyWhat is meant by diagonal relationship?
(N/A) The elements of the second period,such as $Li$,$Be$,and $B$,show similarities in properties with the elements of the third period,such as $Mg$,$Al$,and $Si$,respectively. This similarity in properties between elements placed diagonally in the periodic table is known as the $diagonal \ relationship$.
