Diagonal relationship class 11

The diagonal relationship is owing to the diagonally positioned components having identical polarising power. Byju's Answer. Open in App.

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.

Option 1 Elements of first period. Option 2 Elements of second period. Option 3 Elements of third period. Option 4 b and c both. Correct Answer b and c both. Diagonal relationship between elements refers to the relationship between diagonally adjacent elements in the second and third periods due to similarity in their size. Lithium is different from other alkali metals due to its small size but since its size resembles with that of magnesium, it shows a diagonal relationship with magnesium. Borax, also called sodium borate, sodium tetraborate or disodium tetraborate is basically a salt of weak acid and a strong base. Borax, when dissolved in water, ionizes and hydrolysis of borate ion formed gives HO - and boric acid. Since boric acid is weak acid and sodium hydroxide is strong, the aqueous solution is alkaline in nature. Question Diagonal relationship is shown by. View Answer? Frequently Asked Questions Li shows diagonal relationship with A: Mg B: Be C: Al D: B Solution: Explanation: Diagonal relationship between elements refers to the relationship between diagonally adjacent elements in the second and third periods due to similarity in their size. Final Answer: The correct option is A: Mg.

The elements become more covalent, more electronegative, and less reducing as they advance through the periods. It was revealed by an examination that the charge density of lithium is much closer to that of magnesium than diagonal relationship class 11 those of the other alkali metals.

Stop what you are doing and think about everything that you know about the Periodic Table. You have probably learned that atomic radius of elements decreases across a period and increases down a group, and also that ionization energy and Electronegativity tend to increase across a period and up a group.

You might also remember that elements in the same group have a vertical relationship and show similar physical and chemical characteristics. However, did you know that certain pairs of diagonally adjacent elements possess a diagonal relationship?

Flashcards in Diagonal Relationship 15 Start learning. Ziegler Natta Catalyst In this chapter we will discuss Ziegler natta catalyst, discovery, preparation, mechanism and applications. First, they both have similar electronegativity values: beryllium has an EN value of 1. Introduction In S block elements, there is a diagonal link between adjacent elements in the second and third periods of the periodic table. Stop what you are doing and think about everything that you know about the Periodic Table. 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. At last we will discuss this ziegler natta catalyst. The elements become more covalent, more electronegative, and less reducing as they advance through the periods.

Beryllium shows resemblance with its diagonally opposite element aluminium.

For example, if boron reacts with sodium hydroxide NaOH , it forms sodium borate, whereas if silicon reacts with NaOH, it will form sodium silicate. Boron is a metalloid that is not naturally found in the environment, but it is a part of mineral compounds. Read Edit View history. Points to remember The diagonal neighbors have a lot in common. 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. High-strength springs are made using Cu-Be alloys. Two hydrogen atoms fuse together to form Helium atom and this Helium atom is the second most abundant element. Cengage Learning Asia Pte Ltd.
