Is francium harder than sodium?
Francium is softer than sodium. Francium is a highly reactive metal that is classified as the most electronegative element on the periodic table. Sodium is also a soft metal, but it is harder than francium.
Why is sodium ions reduced to na while calcium does not in the electrolysis of fused nacl infact both ions are present in it. cacl2 to lower the melting point of na?
Sodium ions are reduced to form sodium metal because sodium has a lower reduction potential than calcium. This means it requires less energy to convert sodium ions into sodium metal compared to calcium ions into calcium metal. The presence of CaCl2 in the fused NaCl helps lower the melting point of NaCl, making the electrolysis process more efficient.
Which is more malleable iron or sodium?
Sodium is more malleable than iron. Sodium is a soft metal that can be easily cut with a knife, whereas iron is a harder metal that is less malleable.
What metal reacts more vigorously than calcium?
Sodium reacts more vigorously than calcium when placed in water. When sodium comes into contact with water, it quickly forms sodium hydroxide and releases hydrogen gas, resulting in a rapid and often explosive reaction.
What metal is more reactive sodium or calcium?
Sodium is more reactive than calcium. Sodium has a lower electronegativity and ionization energy compared to calcium, making it more likely to lose electrons and react with other substances. Additionally, sodium's outermost electron is in a higher energy level, making it easier to remove.

Which element is more likely to react with oxygen Sodium or Calcium please explain if you can thank you?
Sodium. Sodium is more reactive than calcium, because sodium has one valence electron whereas calcium has two valence electron. It is easier to lose one electron and react with oxygen and form sodium oxide, compared to losing two electrons and from calcium oxide.
Which one is less malleable Sodium or iron?
Sodium is less malleable than iron. Sodium is a soft metal that can be easily cut with a knife and deformed, while iron is a much harder metal that is more resistant to deformation.
How is sodium metal prepared?
Using Downs process, by the electrolysis of molten sodium chloride. This is done in a Downs Cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 °C. As calcium is less electropositive than sodium, no calcium will be deposited at the cathode. This method is less expensive than the previous Castner process of electrolyzing sodium hydroxide.
Which is softest sodium or lithium?
Lithium is softer than sodium. Sodium is harder because it has a higher atomic number and more electrons, which results in stronger metallic bonding compared to lithium.
What metal is harder than steel?
Tungsten is a metal that is harder than steel.
Which is harder diamond or metal?
Diamond is harder than any metal.
Is calcium higher than sodium in the electrochemical series?
Yes it is. Calcium atom loses electrons more readily in cell reactions than in reactions with air, water and dilute acids.
