What is diagonal relationship between lithium and magnesium?
The diagonally opposite elements possess almost similar electronegativities and therefore almost similar electropositive character. Hence, the main reason of diagonal relationship between lithium and magnesium electronegativity remains constant the same on moving diagonally. So, the correct answer is option C.
What is the diagonal relationship between elements in the periodic table?
The similarity in properties observed between two elements placed diagonally from left to right in two adjacent periods and two adjacent groups in the periodic table is known as the diagonal relationship.
What is modern periodic law explain the diagonal relationship by taking example of lithium and magnesium?
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.
How does lithium and magnesium show similarity?
Lithium shows similarities with magnesium in its chemical behaviour because :
- A. similar size, greater electronegativity and lower polarising power.
- B. similar size, same electronegativity, and lower polarising power.
- C. similar size, same electronegativity and similar high polarising power.
- D. none of the above.
Why Lithium shows diagonal relationship with magnesium what similarity is exhibited between LICL and mgcl2?
Diagonal Relationship of Lithium with Magnesium The main points of similarity : (1) Both have almost similar electronegativities. (2) Both Li and Mg are quite hard. They are harder and lighter than other elements in their respective groups.
In what respect Lithium resembles magnesium or explain diagonal relationship of Lithium and magnesium?
Lithium resembles with magnesium as its charge size ratio is closer to Mg. Its resemblance with Mg is known as diagonal relationship.
Which element shows diagonal relationship with lithium?
magnesium
Lithium shows diagonal relationship with magnesium.
Which set of diagonal relationship is not correct?
Only metals of 2nd period and group 1,2,13 show diagonal relationship. So, C and P do not show diagonal relationship.
Why lithium shows diagonal relationship with magnesium what similarity is exhibited between LICL and mgcl2?
In what respect lithium resembles magnesium or explain diagonal relationship of lithium and magnesium?
What is diagonal relationship Explain with 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.
What is diagonal relationship in what ways Lithium shows similarities to magnesium in its chemical Behaviour any 2 points?
Similarities between lithium and magnesium are as follows. (i) Both Li and Mg react slowly with cold water. (ii) The oxides of both Li and Mg are much less soluble in water and their hydroxides decompose at high temperature. (iii) Both Li and Mg react with N2 to form nitrides.
What is the diagonal relationship of lithium with magnesium?
Diagonal relationship of lithium with magnesium. The main points of similarity : 1) Both have almost similar electronegativities. 2) Both Li and Mg are quite hard. They are harder and lighter than other elements in their respective groups. 3) Both LiOH and Mg(OH)2 are weak bases. 4) Both form ionic nitrides when heated in atmosphere of Nitrogen.
What is diagonal relationship of Li and MG?
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.
Which pair of elements show diagonal relationship?
Q.3. Give examples of diagonal relationship. Ans: The pairs that show diagonal relationship are- Lithium ( Li) of group IA and Magnesium ( Mg) of group IIA, Beryllium ( Be) of group IIA and Aluminium ( Al) of group IIIA, Boron ( B) of group IIIA and Silicon ( Si) of group IIA respectively. Q.4.
Why is lithium a group 1 element?
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. This anomalous behavior of lithium is due to it’s extremely small size it’s ion also. The small size of the Li+ ion leads to its high charge density.
