What colour is radium?
Radium is nearly pure white. When it is exposed to air, though, it immediately oxidizes, turning black. The heaviest of the alkaline earth metals, radium is a chemical element whose atoms - like those of the other alkaline earth metals - have two electrons in their outermost shell; this causes them to react readily and form numerous compounds. The luminescent quality in radium made it ideal for use in self-luminous paints for watches, instrument dials, clocks and the like. Unaware of the danger of the extreme radioactivity of the element, many watch-dial painters who shaped their paintbrushes by putting them between their lips, died from the extended exposure to the radium in the paint. With its hazards come benefits. Today, radium is used medically to treat some kinds of cancer. On this date in 1898, scientists Pierre and Marie Curie and Gustave Bemont discovered radium in pitchblende that came from the now Czech Republic.Radium has probably a silvery metallic appearance.
Whose research led to the discovery of base pairing A-T and C-G in nucleic acids?
Austrian chemist Erwin Chargaff's research.
Why radium shine in night its ans?
Radium is a radioactive element which emits an ionizing radiation. By definition, ionizing radiation ionizes nearby atoms (strips one or more electrons from them). This leaves the atom (Radium or others) with a positive charge (an attractor of electrons). As a stray electron finds this newly created ion and reenters the atom's orbitals, it releases photons whose energies are related to the orbitals. These released photons are the "Shining" observed.
What did galileo see when he observed jupiter through his telescope?
Jupiter and eventually 4 moons whose position relative to Jupiter changed from night to night.
What were Marie curie contributes?
She contributed to cancer research by discovering radium, whose gas can heal scar tissue. Also, in World War 1, she got together dozens of trucks, called "Little Curies" and filled them with donated x-ray equipment, saving over a million lives. She discovered polonium, radium, and coined the word radioactivity. She was also the first female to win a nobel prize, and the first person ever to win two nobel prizes. She was also the first female professor at Sorbonne University, in Paris.
Whose discovery of radium changed the worlds view of the atoms?
Radium was discovered by the Curies in France in 1898, in samples of pitchblende which were found to be radioactive after removal of the uranium.
