What is diagonal relationship why lithium shows diagonal relationship with magnesium?

Lithium shows diagonal relationship with Magnesium. 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.

Which elements shows diagonal relationship with lithium?

Lithium shows diagonal relationship with magnesium. Beryllium shows diagonal relationship with aluminum. Boron shows diagonal relationship with silicon. Hence, the correct answer is the option (A).

Why lithium shows diagonal relationship with magnesium what similarity is exhibited between LiCl and MgCl2?

Lithium and magnesium show diagonal relationship as they have same polarizing power so elements of second period shows similarities with elements of third period of next group. 3)Due to small size of li and Mg their hallides are soluble in organic solvents. 4)They form hydrates like LiCl. H2O and MgCl2.

How is lithium similar to magnesium?

– Lithium from the second period of group 1 and Magnesium from the third period of group 2 forms carbonates which dissociates and forms carbon dioxide. Like Magnesium, lithium also reacts directly with nitrogen and forms nitrides. -This is because the ratio of their charge to size is nearly the same.

Does B and P show diagonal relationship?

Diagonal relationship is shown by the elements which belong to the second period and elements which belong to the third period in the periodic table. Boron and magnesium are not diagonally with each other and will not show diagonal relationship.

What is diagonal relationship explain with two examples?

A diagonal relationship in S-block elements exists between adjacent elements which are located in the second and third period of the periodic table. For example, Lithium of group 1A and second period shows similarities with the properties of magnesium which are located in the 2nd group and 3rd period.

Is Lithium show diagonal relationship with Aluminium?

Lithium shows diagonal resemblance with aluminium due to similar charge to size ratio.

Is Polarising power of lithium and magnesium same?

On moving diagonally in the periodic table, the polarising power i.e. ratio of the ionic charge and square of the ionic radius is nearly same for the Lithium and Magnesium (ionic charge and ionic radius of Li and Mg are +1 and +2 and 60pm and 65pm respectively) and accounts for the similarities between the properties …

What are points of similarities between lithium and magnesium any three?

Similarities between Lithium and Magnesium are • Both are quiet hard. The hydroxides of both the elements are weak bases and decompose on heating. Both of these elements have covalent character. Chlorides of these elements are soluble in ethanol.

Are lithium and magnesium in the same period?

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. These pairs (lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si), etc.)

Does C and P show diagonal relationship?

Only metals of 2nd period and group 1,2,13 show diagonal relationship. So, C and P do not show diagonal relationship.

What is diagonal relationship give example?

What is the relationship between lithium and magnesium?

This property is named as Diagonal Relationship. Lithium exhibits most of the characteristic properties of the group 1 elements, but it differs in many respects from them and resemble with Magnesium which is Diagonal to it in Periodic Table.

What is the relationship between MG and Li?

ANOMALOUS BEHAVIOR OF Li AND DIAGONAL RELATIONSHIP WITH Mg: It is observed for 3 elements of periodic table that they resemble more with their diagonal element than their same group elements. This property is named as Diagonal Relationship.

Why is there a diagonal relationship between lithium and sodium?

Beryllium is smaller than Lithium. Sodium is larger than Lithium. Thus Sodium is much larger than Beryllium. Therefore diagonal relationship does not work in this direction. So you now understand that diagonal relationship is because of the similar sizes of atoms; it is not about drawing a geometric diagonal in the PT.

How are lithium and magnesium not solid bicarbonates?

The Li2O and MgO thus formed do not combine with excess O2 to form peroxide and superoxide. 7) The carbonates of these metals decompose on heating to the corresponding oxides with the evolution of carbon dioxide. 8) Both Lithium and magnesium do not form solid bicarbonates.
