Elements that are named after countries are Francium, Gallium and Germanium. Gallium is one of the few metals besides mercury and cesium that is a liquid at room temperature. It was named after the Latin word for France, "Gallia."Know More
Gallium's atomic number is 31, and when it is especially pure, it has a brilliant silver sheen. It doesn't occur freely in nature but is found in ores of zinc and bauxite. Its melting point is so low, about 85.6 degrees Fahrenheit, that it melts in a person's hand. It also alloys with most metals. Gallium is mostly used in electronics, LEDs and high-temperature thermometers.
Francium was also named for France. It is also one of the few elements to have been discovered by a woman. It was discovered by Marguerite Perey in 1939. Francium is formed by the breakdown of actinium and has an atomic number of 87. It is very radioactive and can itself break down into astatine, radium and radon.
Germanium is considered a semi-metal. Its atomic number is 32, and it was named after the country of Germany. It was discovered by Clemens Winkler in 1886 and is largely used for semiconductors and also in infrared instruments.Learn more about Atoms & Molecules
The element curium is named after both Pierre and Marie Curie. The Curies discovered the elements polonium and radium; Marie was awarded the Nobel Prize for these discoveries in 1903. Curium was named in honor of their contributions to the field of radioactivity.Full Answer >
The noble gas argon was named by its discoverers, Baron Rayleigh and William Ramsay, in 1894. The name comes from the Greek word argon, the neuter form of the word argos, which means lazy, idle and living without labor. It was so named because of its inert qualities.Full Answer >
Aluminum, or aluminium, was named after alum, a mineral known and used since antiquity. In 1761, French chemist Louis-Bernard Gutyon de Morveau proposed the name "alumine" for the base chemical of alum, even though it had yet to be isolated.Full Answer >
