Hence the name may have arrived in England after the Norman Conquest of 1066. The surname may also have derived as a nickname for a man with strikingly glossy black hair or for one with a raucous voice, from the Middle English or the Old French Corbin Corbun, raven. The personal name was recorded as Corbin(us) in the Domesday Book of 1086 in Warwickshire and Kent.
Have you ever wondered what about the other elements in the sun? I hunted up a table (source: NASA-Goddard Space Flight Center) listing the sun's elemental composition, which we know from analysis of its spectral signature. I'm sure you're not surprised that hydrogen is the most abundant element. The sun is constantly fusing hydrogen into helium, but don't expect the ratio of hydrogen to helium to change anytime soon. The sun is 4.5 billion years old and has converted about half of the hydrogen in its core into helium.
Long recognized in compounds, sodium was first isolated by Davy in 1807 by electrolysis of caustic soda. Sources. Sodium is present in fair abundance in the sun and stars. The D lines of sodium are among the most prominent in the solar spectrum. Sodium is the fourth most abundant element on earth, comprising about 2.6% of the earth's crust; it is the most abundant of the alkali group of metals. It is now obtained commercially by the electrolysis of absolutely dry fused sodium chloride.
