What does «Na» mean in Spanish?
- Chemical symbol for the element sodium. It is "Na" because it comes from the Latin word natrium. Atomic number 11, it belongs to the alkali metals. Sodium was isolated by Sir Humphry Davy in 1807; very abundant in nature as it is found in sea salt (in large quantities in ionic form) and in the mineral halite. The earth's crust contains approximately 2.6% sodium, making it the sixth most abundant element. It is a soft, silvery alkali metal with an oily consistency. It is highly reactive, burning with a yellow flame; it oxidizes with oxygen and reacts violently with water.
Examples of use in Spanish: "La aleación Na K se emplea para la transferencia de calor además de desecante para disolventes orgánicos y como reductor".
