Facts about sodium
Here are a few interesting facts about sodium element.
- Sodium is a soft metal and it can be cut with a knife.
- Sodium floats on water because it has less density than that of water.
- Sodium is also present in the human body, and it maintains the fluid balance in the body cells.
- Sodium is the most abundant alkali metal.
- Sodium is the 6th most abundant element found from the earth’s crust.
- Around 2.3% of the earth’s crust contains sodium element.
Properties of sodium
Here is a list of some physical properties and chemical properties of sodium.
Physical properties of sodium
- Sodium is a soft metal having a silvery white appearance.
- It is soft metal and it can be cut with a knife.
- Sodium metal is a good conductor of electricity as it has only 1 valence electron.
- The melting point and boiling point of sodium are 97.7 °C and 882.9 °C respectively.
- There are many isotopes of sodium, but out of those isotopes, the most stable isotope is 23Na.
Chemical properties of sodium
- Sodium is a reactive metal and it forms an oxide layer if kept open in the air.
- As sodium is a reactive metal, it is not found in free state. But it is always found in the compound with other elements.
- When sodium metal is burnt in a flame, it produces a golden-yellow flame.
- The sodium has an electron configuration [Ne] 3s1 and it has only 1 valence electron.
- Sodium forms various compounds like NaCl, Na2CO3, NaOH, NaNO3, etc.
Uses of sodium
Here are some uses of the sodium element.
- Sodium is largely used in making NaCl, Na2CO3, NaOH and other useful compounds.
- Sodium bicarbonate is used in baking as well as in sodablasting.
- Sodium has a high thermal conductivity and so the liquid sodium metal is used as a heat transfer fluid in sodium-cooled fast reactors.
