This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element.
Which element has similar properties to lithium explain?
Why does beryllium have similar properties to Lithium? Elements in the same group have the same number of electrons in their outermost shell hence their chemical properties are usually similar to one another.
Which element of group II is similar to lithium?
In many respects lithium also shows similarities to the elements of the alkaline-earth group, especially magnesium, which has similar atomic and ionic radii.
Do I and CA have similar properties?
Calcium and potassium are both metals. … Calcium and potassium have a different number of valence electrons. Correct! Elements within in the same group/family have similar chemical properties due to the fact that they have the same number of valence electrons.
How does sodium have similar properties to lithium?
Li, Na and K all ended up in the Alkali Metals group because of this pattern that grouped similar elements. They have similar chemical properties because they all have one valence electron which they lose easily to form a +1 ion. They all react vigorously with water to form hydrogen gas and hydroxide ion.

Why is lithium similar to beryllium?
Both beryllium and lithium are in the same period, period 2. However, they are in two different groups in the periodic table. Therefore, they have different properties. Both these chemical elements are s-block elements because they have their valence electrons in s orbitals.
Which is more electropositive lithium or beryllium?
Thus Beryllium (Be) is the Most electropositive element among them.
Do beryllium and lithium have similar properties?
What Physical Properties are Common in Lithium and Beryllium? Though Lithium and Beryllium belong to two different groups in the periodic table, both have some similarities in them. These are partially soluble in the water and exhibit large atomic radii.
Why is lithium anomalous Behaviour?
Lithium shows anomalous behavior due to its small size. The polarizing power of lithium ion is highest of all the alkali metal ion . Because of small size, Lithium is very hard, less reactive as compare to other alkali metals like sodium and potassium.
Is potassium similar to sodium?
The chemical properties of potassium are similar to those of sodium, although the former is considerably more reactive.
Is Sodium more like lithium or magnesium?
Are the properties of sodium, Na, more like the properties of lithium, Li, or magnesium, Mg? … lithium – Sodium and lithium are in the same group, so their properties should be more alike than the properties of sodium and magnesium.
What is chemically similar to CA?
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium.
Why do NA and CA have similar properties?
Explanation: Chemical “properties” are based on their electron structure, and it is how the Periodic Table of the Elements is constructed. … So, the elements with similar properties to sodium (Na) are all of those elements in the same Group. The ones “most” similar would be the ones closest in mass as well.
What is the highest electronegativity value?
Of the main group elements, fluorine has the highest electronegativity (EN = 4.0) and cesium the lowest (EN = 0.79). This indicates that fluorine has a high tendency to gain electrons from other elements with lower electronegativities. We can use these values to predict what happens when certain elements combine.
What form of potassium is best for high blood pressure?
Our results, in conjunction with the evidence from many previous trials that potassium chloride has a significant blood pressure-lowering effect, suggest that potassium citrate has a similar effect on blood pressure as potassium chloride.
Why are sodium and potassium kept in kerosene?
Hint: Sodium and potassium are highly reactive metals. They react vigorously with air and water. A large amount of heat is produced in their reaction. … To avoid such accidents these metals are kept immersed in kerosene oil.
What are symptoms of low potassium?
- Muscle twitches.
- Muscle cramps or weakness.
- Muscles that will not move (paralysis)
- Abnormal heart rhythms.
- Kidney problems.
Does magnesium have similar properties to sodium?
Magnesium and sodium appear next to each other in the third horizontal row, making them period three elements. Together, they form the S-block of this period. This means that their highest-energy electron is in the S-orbital shell. … Like magnesium and sodium, their outer electrons are all in the S shell.
What elements have similar properties?
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.
Does lithium has high Polarising power?
Lithium ion (Li⁺) has the maximum polarizing power. The reason is that lithium atom is very small and therefore the ratio of charge per unit area is very high. The high positive charge density can attract the electron cloud on the hallide ion towards the lithium atom.
Why are lithium salts commonly hydrated?
Lithium is the smallest in size among the alkali metals. Hence, Li+ ion can polarise water molecules more easily than other alkali metals. As a result, water molecules get attached to lithium salts as water of crystallization. Hence, lithium salts such as trihydrated lithium chloride are commonly hydrated.
