Question

What are the points of similarities between Li and Mg (i.e. diagonal relationship) ?

Answer 1

ANSWER.......


☆☆ Similarities ☆☆


¤ Both Li and Mg are harder and lighter than other elements of their respective groups.


¤ Both are reacts slowly with water.


¤ The oxides of both do not form Superoxides i.e. Li2O and MgO do not form superoxides.


¤ The chlorides of both i.e. LiCl MgCl2 are soluble in ethanol.


¤ Both form crystals like LiCl.2H2O and
MgCl2.8H2O .

Answer 2

Heya!
____

_________________________________________________________

→Firstly , let's know what is a Diagonal Relationship ?

=> The similarities in the properties of elements present diagonally is called a Diagonal Relationship . For Example -


◼Lithium and magnesium

◼Boron and Silicon

◼Beryllium and Aluminium .


=> Similarities between Lithium and Magnesium are -



→Both lithium and magnesium are harder than the rest of the members of their respective groups .


→Both show least stability towards heat .


→Their reaction with water is quite slow.


→Also , both of these form mono oxides.


→Both are unable to form super oxides .
