Know Everything About Sodium

✒️ Introduction about Sodium

🔴 Sodium is a soft, silvery color, and highly reactive alkali metal.

🔴 In the periodic table, Sodium is kept in group 1, as it has single electron in its outer shell.

🔴 The symbol of sodium is ‘Na,’ which has been actually taken from Latin word ‘natrium.’

🔴 Sodium exists in various minerals including feldspars, sodalite, and rock salt (NaCl).

🔴 In 1807, Humphry Davy first isolated sodium by the electrolysis of sodium hydroxide.

🔴 By the time, 20 isotopes of sodium are known, but among all, only 23Na is stable.

🔴 In terms of abundance, sodium is the sixth element found in the Earth's crust.

✒️ Salient Features of Sodium

🔴 Sodium metal a soft element that be can be easily cut with a knife.

🔴 Sodium is a good conductor of heat and electricity.

🔴 Because of having low atomic mass and large atomic radius, sodium is one of the least dense elements (third least dense element – first two are lithium and potassium).

🔴 Sodium can float on water.

🔴 Sodium along its compounds glow yellow (see image below).

🔴 Sodium compounds have very high commercial importance and have high demand in the industries of glass, paper, soap, and textiles.

✒️ Occurrence of Sodium

🔴 Sodium does not found as a pure element, as it is highly reactive.

🔴 The crust of Earth contains about 2.27% sodium.

🔴 Sodium is the 5th most abundant metal; other four are aluminum, iron, calcium, and magnesium.

🔴 In the oceanic water, about 1.08 × 104 milligrams sodium found in per liter.

✒️ Uses of Sodium

🔴 Metallic sodium is principally used for the production of sodium borohydride, sodium triphenylphosphine, azide, indigo, etc.

🔴 In cooking, sodium bicarbonate is used.

🔴 Sodium and some of its compounds are used in medicines.

🔴 In comparison to potassium (which is a better ion), sodium is more frequently used because of its lower price and atomic weight.

🔴 In organic chemistry, sodium hydride is used as various reaction.

🔴 In some fast reactors, liquid sodium is used as a heat transfer fluid because of having the property of good heat conductivity.

🔴 Sodium is also an essential mineral for the human health, as it regulates blood pressure, blood volume, osmotic equilibrium, and pH value.

🔴 The minimum amount of 500 milligrams sodium is required every day for a healthy human body.

🔴 Sodium chloride is highly useful for anti-icing and de-icing as well as a preservative.
