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.

What is diagonal relationship in the periodic table?

Diagonal relationship is formed due to the identical size of ions. As we move towards right across a period in the periodic table, then the size of the atom reduces, and when we move downward across a group then the size of the atoms gradually increases.

What is diagonal relation in maths?

The diagonal relation on S is a relation ΔS on S such that: ΔS={(x,x):x∈S}⊆S×S. Alternatively: ΔS={(x,y):x,y∈S:x=y}

What is the reason for diagonal relationship?

Reason. The diagonal relationship is due to the polarizing power, that is, ionic charge/ionic radius, being similar for the diagonally placed elements.

What is diagonal relationship class 11th?

The similarity in the properties of definite pairs of diagonally adjacent elements in the second and third periods of the periodic table is called diagonal relationship.

Which of the following shows a diagonal relationship?

Second-period elements such as Lithium, Beryllium, Boron show a diagonal relationship with third-period elements. So, this relationship is called a diagonal relationship. Lithium and magnesium are diagonally related.

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 diagonal relationship class 10 CBSE?

A diagonal relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table. For example: Li and Mg have diagonal relationship ; Be and Al ; B and Si exhibit diagonal relationship.

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.

Do C and P show diagonal relationship?

Does carbon and phosphorus show diagonal relationship?

Both carbon and phosphorous has diagonal relationship. –>Like carbon , phosphorous also exhibits allotropes. –> Electronegativity of carbon is 2.544 and phosphorous is having 2.253 on pauling scale.

Do be and Al Show diagonal relationship?

Beryllium shows resemblance with its diagonally opposite element aluminium. Points of similarity are: (3) These two elements have same electronegativity and the polarising power i.e. charge/ radius ratio of their ions are very similar. …

What is an example of a diagonal relationship?

A Diagonal Relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table. These pairs (Li & Mg, Be & Al, B & Si etc.) exhibit similar properties; for example, Boron and Silicon are both semiconductors, form halides that are hydrolyzed in water and have acidic oxides.

What is the cause of diagonal relationship?

A diagonal relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table. Such a relationship occurs because moving left to right and descending top to bottom in the periodic table have opposing effects.

What is diagonal relationship in periodic table?

Diagonal relationship. 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…

Are diagonal lines parallel?

If the lines are known to be diagonal then only 2 cases exist: The lines are parallel. The lines are perpendicular.
