Answers
Explanation:
in a diagonal relationship the properties of the element does not resemble with the properties of other metals of the group...
the properties of lithium and magnesium are similar from many aspects...
both never reacts with exceed of oxygen to form superoxide...
they forms nitrides
Answer:
A diagonal relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods (first 20 elements) of the periodic table.
Explanation:
Due to its small size lithium differs from other alkali metals but resembles magnesium, as its size is closer to lithium.
Diagonal relationship is formed due to the identical size of ions.
As we move downward across a group in the periodic table then the size of the atoms gradually increases.
As we move towards right across a period in the periodic table, then the size of the atom reduces.
