![]() Sodium is largely used in making NaCl, Na 2CO 3, NaOH and other useful compounds.Here are some uses of the sodium element. Sodium forms various compounds like NaCl, Na 2CO 3, NaOH, NaNO 3, etc.The sodium has an electron configuration 3s 1 and it has only 1 valence electron.When sodium metal is burnt in a flame, it produces a golden-yellow flame.But it is always found in the compound with other elements. As sodium is a reactive metal, it is not found in free state. ![]() Sodium is a reactive metal and it forms an oxide layer if kept open in the air.There are many isotopes of sodium, but out of those isotopes, the most stable isotope is 23Na.The melting point and boiling point of sodium are 97.7 ☌ and 882.9 ☌ respectively.Sodium metal is a good conductor of electricity as it has only 1 valence electron.It is soft metal and it can be cut with a knife.Sodium is a soft metal having a silvery white appearance.Here is a list of some physical properties and chemical properties of sodium. Around 2.3% of the earth’s crust contains sodium element.Sodium is the 6 th most abundant element found from the earth’s crust.Sodium is the most abundant alkali metal.Sodium is also present in the human body, and it maintains the fluid balance in the body cells.Sodium floats on water because it has less density than that of water.Sodium is a soft metal and it can be cut with a knife.Here are a few interesting facts about sodium element.

The important data related to sodium element is given in the table below. Uses of Sodium Sodium Element (Information Table). ![]() ![]() There is a lot more information related to sodium which is mentioned in the Information Table given below. Sodium is in the s-block and it is classified as an alkali metal on the periodic table. Sodium element (Na) is in group 1 and period 3 of a periodic table. ![]()
