Diagonal relationship class 11

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, diagonal relationship class 11.

You might also remember that elements in the same group have a vertical relationship and show similar physical and chemical characteristics.

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.

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?

Beryllium and Aluminum also have a diagonal relationship.

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.

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. Points to remember The diagonal neighbors have a lot in common. As you proceed from left to right and along with the group there will be a noticeable change in their relationship. Many atomic properties change in distinct ways down groups and across periods of the Periodic Table, resulting in diagonal correlations. The elements of the s and p-block elements have diagonal relationships in addition to group and period relationships. Explanation The elements show some similarities when going diagonally across the periodic table, but they are far less evident than the similarities within a group.

Ans: Alloys can be made from Be, which is a chemical element. They are not as noticeable after B and Si. Two hydrogen atoms fuse together to form Helium atom and this Helium atom is the second most abundant element. These correlations are known as diagonals. The most abundant element in the universe is A: helium B: oxygen C: silicon D: hydrogen Solution: Explanation:- Hydrogen is the most abundant element in the universe; it is present in every Star.
