The elements sodium and lithium have similar chemical properties because they both have the same…
Why do lithium and magnesium have similar properties?
The elements having diagonal relationship show similar properties and the reason is because the both of them will have similar electronegativity and polarising power i.e. charge per size ratio of both the elements are nearly the same.
Is lithium similar to beryllium?
They both show similarity in properties of the second element of the following group. That means, in these anomalous properties they resemble the second element of the following group. Thus lithium shows similarities to magnesium and beryllium to aluminium in many of their properties.
Which element is directly related to lithium?
The alkali metals are also called the lithium family, after its leading element. Like the other alkali metals (which are sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr)), lithium has a single valence electron that is easily given up to form a cation.
How does Li differ from other alkali metals in their chemical properties give reason for this anomalous behaviour of Li 3?
Lithium is harder than other alkali metals. Melting and boiling point is higher than other alkali metals. Out of all the other alkali metals, it is the least reactive metal. It is a strong reducing agent compared to other alkali metal.
What are lithium anomalous properties?
Anomalous behaviour of lithium with respect to other alkali metals: The melting point and boiling point of lithium are higher that than other alkali metals. The hardness of lithium is higher than other metals. Lithium nitrate decomposes to form an oxide whereas other metals on heating give nitrites.
Why are chemical properties of Li and Mg similar Mcq?
Explanation: Chemical properties of lithium and magnesium are similar because both have same isonisation potential.
Why is lithium and magnesium diagonally related?
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.
Why Al and be resemble in some of their properties?
Be resembles Al because charge over radius ratio is similar, i.e., they have similar polarizing power.
Do elements have similar properties?
Elements in the same column of the Periodic Table have similar chemical properties. So what does that mean about their valence electrons? You guessed it! Elements in the same column of the Periodic Table have the same number of valence electrons – that's why they have similar chemical properties.
Why is lithium different from other alkali metals?
The key difference between Lithium and other alkali metals that we can tell is that the lithium is the only alkali metal that can react with nitrogen whereas the other alkali metals cannot undergo any reaction with nitrogen. Moreover, lithium cannot form an anion while other alkali metals can form anions.
What properties of lithium differ it from the rest of the alkali metals?
Solution : The unusual properties of lithium as compared to other alkali metals is due to (i) the exceptionally small size of its atom and ion, (ii) high polarising power (charge/size ratio) , (ii) high ionization enthalpy and (iv) absence of d-orbitals .
What makes lithium unique than other metals?
Lithium is a special metal in many ways. It's light and soft — so soft that it can be cut with a kitchen knife and so low in density that it floats on water. It's also solid at a wide range of temperatures, with one of the lowest melting points of all metals and a high boiling point.
Why and in what ways does lithium resemble Group 2 metals?
In its chemical reactivity, lithium more closely resembles Group 2 (IIa) of the periodic table than it does the other metals of its own group. It is less reactive than the other alkali metals with water, oxygen, and halogens and more reactive with nitrogen, carbon, and hydrogen.
In what Rays lithium shows similarities to Mg in its chemical behavior?
Similarities between lithium and magnesium are as follows. Both Li and Mg react slowly with cold water. The oxides of both Li and Mg are much less soluble in water and their hydroxides decompose at high temperatures. Both Li and Mg react with N2 to form nitrides.
How are Li and Mg related to each other in the periodic table write the name of another pair having such a relationship?
Answer: 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.) … Such a relationship occurs because crossing and descending the periodic table have opposing effects………….
Why lithium and magnesium shows the diagonal relationship explain with reason and example?
The electronegativities of Li is 1.0 and Mg is 1.2. They are low and almost same. Their ionic radii are similar. Hence they show similarities which is known as diagonal relationship between first element of a group with the second element in the next higher group.
What do magnesium and lithium have in common?
Diagonal Relationship of Lithium with Magnesium The main points of similarity : (1) Both have almost similar electronegativities. (2) Both Li and Mg are quite hard. They are harder and lighter than other elements in their respective groups.
