3History. The name derives
from the English soda and Latin sodanum for “headache remedy”
. The symbol Na derives from the Latin natrium for “natron” (soda in English). Sodium was discovered in 1807 by the English chemist Humphry Davy from electrolysis of caustic soda (NaOH).
Why is Natrium called sodium in English?
Sodium’s Latin name, ‘natrium’,
derives from the Greek ‘nítron’ (a name for sodium carbonate)
. … A number of modern languages still call the element natrium instead of sodium, and it’s this name that its chemical symbol, Na, comes from.
Is Natrium same as sodium?
| Sodium | Symbol “Na”: from New Latin natrium, coined from German Natron, ‘natron’ | Main isotopes of sodium |

What is Natrium used for?
Sodium is used
as a heat exchanger in some nuclear reactors
, and as a reagent in the chemicals industry. But sodium salts have more uses than the metal itself. The most common compound of sodium is sodium chloride (common salt). It is added to food and used to de-ice roads in winter.
Why is Kalium called potassium?
The word potassium stems from the English “pot ash,” which was used to isolate potassium salts. We get K from the name kalium, given
by the German chemist Martin Heinrich Klaproth
, which stemmed from alkali, which stemmed from the Arabic al-qalyah, or “plant ashes.”
Is pure sodium toxic?
Sodium is essential to human health, but
too much sodium is poisonous
. Sodium poisoning can cause seizures, coma, and death.
What color is sodium?
Sodium is a very
soft silvery-white metal
. Sodium is the most common alkali metal and the sixth most abundant element on Earth, comprising 2.8 percent of Earth’s crust.
Why sodium is bad for you?
Your body needs a small amount of sodium to work properly, but too much sodium can be bad for your health. Diets higher in sodium are associated with an
increased risk of developing high blood pressure
, which is a major cause of stroke and heart disease.
Is Natrium good for health?
Despite its continued vilification,
sodium is a necessary nutrient for good health
. It’s one of your body’s electrolytes, which are minerals that create electrically charged ions. A major source of sodium in most diets is added salt in the form of sodium chloride — which is 40% sodium and 60% chloride by weight ( 1 ).
What foods are naturally high in sodium?
- Smoked, cured, salted or canned meat, fish or poultry including bacon, cold cuts, ham, frankfurters, sausage, sardines, caviar and anchovies.
- Frozen breaded meats and dinners, such as burritos and pizza.
- Canned entrees, such as ravioli, spam and chili.
- Salted nuts.
- Beans canned with salt added.
How do humans use sodium?
The body uses sodium
to control blood pressure and blood volume
. Your body also needs sodium for your muscles and nerves to work properly.
What is a person’s normal sodium level?
It helps maintain normal blood pressure, supports the work of your nerves and muscles, and regulates your body’s fluid balance. A normal blood sodium level is
between 135 and 145 milliequivalents per liter
(mEq/L). Hyponatremia occurs when the sodium in your blood falls below 135 mEq/L.
What makes sodium unique?
It’s a
soft metal
, reactive and with a low melting point, with a relative density of 0,97 at 20oC (68oF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.
Where is potassium found on Earth?
Most potassium occurs
in the Earth’s crust as minerals
, such as feldspars and clays. Potassium is leached from these by weathering, which explains why there is quite a lot of this element in the sea (0.75 g/liter). Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite.
What is potassium in the body?
Potassium is
a mineral
that your body needs to work properly. It is a type of electrolyte. It helps your nerves to function and muscles to contract. It helps your heartbeat stay regular. It also helps move nutrients into cells and waste products out of cells.
What causes low potassium blood?
- Frequent vomiting and/or diarrhea, including diarrhea from abusing laxatives.
- Excessive sweating.
- Drinking too much alcohol.
- Drugs, including diuretics (which cause urination), antibiotics, and corticosteroids.
- Not taking in enough potassium due to a poor diet (less common)
