Diagonal relationship class 11

Option 1 Elements of first period. Option 2 Elements of second period. Option 3 Elements of third period.

When the properties of definite pairs of diagonally adjacent elements in the second and third periods of the periodic table are comparable, this is referred to as a diagonal relationship, and it is defined as follows: Lithium is the first element of Group 1 in s-block elements, whereas Beryllium is the first element of Group 2 in s-block elements. Diagonal relationship refers to the resemblance in attributes between two elements that are diagonally adjacent in the second and third period of the periodic table. Beryllium is the first element in Group 2 of the s-block elements, while Lithium is the first element in Group 1. Because of the similarities in ionic sizes and radius ratio of the elements, their properties reflect those of the second element in the following group. As a result, lithium and magnesium share comparable qualities, whereas Beryllium and Aluminium do. In the second and third periods of the periodic table, there is a diagonal link between some pairs of diagonally adjacent elements that can be seen.

Diagonal relationship class 11

In chemistry 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. The organization of elements on the periodic table into horizontal rows and vertical columns makes certain relationships more apparent periodic law. Moving rightward and descending the periodic table have opposite effects on atomic radii of isolated atoms. Moving rightward across the period decreases the atomic radii of atoms, while moving down the group will increase the atomic radii. Similarly, on moving rightward a period, the elements become progressively more covalent [ clarification needed ] , less basic and more electronegative , whereas on moving down a group the elements become more ionic , more basic and less electronegative. Thus, on both descending a period and crossing a group by one element, the changes "cancel" each other out, and elements with similar properties which have similar chemistry are often found — the atomic radius, electronegativity, properties of compounds and so forth of the diagonal members are similar. It is found that the chemistry of a period 2 element often has similarities to the chemistry of the period 3 element one column to the right of it in the periodic table. Thus, the chemistry of Li has similarities to that of Mg, the chemistry of Be has similarities to that of Al, and the chemistry of B has similarities to that of Si. These are called diagonal relationships. They are not as noticeable after B and Si. The reasons for the existence of diagonal relationships are not fully understood, but charge density is a factor.

There are three diagonal relationships in the periodic table.

The diagonal relationship is owing to the diagonally positioned components having identical polarising power. Byju's Answer. Open in App. Introduction In S block elements, there is a diagonal link between adjacent elements in the second and third periods of the periodic table. When compared to the other components in the sub-group to which they belong, the attributes of s block elements differ dramatically.

Does boron and silicon have a diagonal relationship? View Answer? Stop what you are doing and think about everything that you know about the Periodic Table. Which of the following elements have a diagonal relationship with lithium Li? Also, they both combine with Nitrogen to form nitrides. For example, magnesium Mg has an atomic number of 12, and an atomic mass of Thus, the chemistry of Li has similarities to that of Mg, the chemistry of Be has similarities to that of Al, and the chemistry of B has similarities to that of Si. Archived from the original PDF on Contents move to sidebar hide. For example, the elements in Group 1 except for hydrogen are called Alkali Metals. Solution: Explanation:.

Beryllium shows resemblance with its diagonally opposite element aluminium. Points of similarity are:.

Creating flashcards. When combined with other elements, boron can be used in the armor of military tanks boron carbide and also in the manufacture of household cleaners borax salt. Question Diagonal relationship is shown by. Thus, on both descending a period and crossing a group by one element, the changes "cancel" each other out, and elements with similar properties which have similar chemistry are often found — the atomic radius, electronegativity, properties of compounds and so forth of the diagonal members are similar. Hydrated crystal LiCl 2 H 2 O of lithium chloride is isolated from the lithium chloride. The oxides and hydroxides of beryllium and magnesium are considered amphoteric , meaning that they can react both as acids or bases. The Chemical Equations below show the reaction of boron and silicon with magnesium metal Mg. Ans: lithium shares many qualities with magnesium, and beryllium shares many properties with aluminium. Which of the following elements have a diagonal relationship with lithium Li? Link copied! Test your knowledge with multiple choice flashcards. Yes, B and Si have a diagonal relationship. In covalent bonding, two atoms share a pair of electrons to acquire a full outer shell. Taking a short quiz.
