ammonia  the modern names of many chemical elements and compounds have their origins in the obscure lore of the ancient world. In Egyptian mythology, Amen was a god variously represented as a ram with great horns, as a creature with a ram's head and a human body, or as simply a man-either enthroned or standing. To the Greeks, Amen became known as Ammon. His chief temple and oracle were at an oasis in the Libyan desert near Memphis. It is said that near this temple a cesspool was located, where the urine of camels was collected. For centuries in Egypt camel's urine, soot, and sea salt were heated together to form sal ammoniac, which in its Latin form literally means "salt of Ammon."To designate the gas produced when sal ammoniac is heated with an alkali, the Swedish chemist Torbern Olof Bergman in 1782 coined the New Latin term ammonia. In less than two decades ammonia entered English. SupeSite/X-Space官方站1\/m9Y9v5h!b#v

        In Greek mythology Cadmus was the reputed founder of the Greek city of Thebes. His most celebrated exploit was his battle with a man-eating dragon. After slaying the monster, he removed its teeth and sowed some of them in the ground. From these sown teeth sprang up a company of armed men. Cadmus reacted by surreptitiously striking them with stones; the men, suspecting one another, began a mutual slaughter until only five remained. With these five men Cadmus founded his new city of Thebes. The ancient citadel of Thebes was named Cadmea in his honor. It was in this Greek city that the ancients first discovered the sustance known to us as zinc oxide. For zinc oxide, or for any ore abounding in zinc, the ancients used the Latin word Cadmia, after Thebes's legendary founder. It was not until centuries later, in 1817, that the German chemist Friedrich Stromeyer discovered the presence of another metal in a zinc compound, which in his case happened to be zinc carbonate. Stromeyer called this new discovery cadmium, the old name for any zinc-rich ore.[separator]SupeSite/X-Space官方站RN}h9T.X ?

        Niobe was the daughter of the Lydian king Tantalus in Greek mythology. She is most famous as the proud mother of twelve children who insulted the goddess Leto. For her affront, all of her children were killed. She grieved bitterly, and even after she was turned into a block of marble, a stream of tears continued to flow. Her father, Tantalus, was the subject of an even more famous myth. For his offenses against the gods, he was condemned to perpetual thirst is Hades, even though he was standing chin-deep water. Whenever he attempted to drink the water, the prize receded just out of reach. Appropriately, the metallic element tantalum was named after him because its inability to absorb acid suggested the kng's component. When niobium was first identified, it was discovered in tantalite, so it was only fitting that the metallic element be named after the daughter of the parched king.SupeSite/X-Space官方站2RK)XW*YjyC
