Neptunium is a chemical element; it has symbol Np and atomic number 93. A radioactive actinide metal, neptunium is the first transuranic element. It is named after Neptune, the planet beyond Uranus in the Solar System, which uranium is named after. A neptunium atom has 93 protons and 93 electrons, of which seven are valence electrons.
The link (usually abbreviated as "l.", "li." or "lnk."), sometimes called a Gunter’s link, is a unit of length formerly used in many English-speaking countries. In US customary units modern definition, the link is exactly 100 of a US survey foot, [1] or exactly 7.92 inches or 20.1168 cm. The unit is based on Gunter's chain, a metal chain 66 ...
The Highway 237 Bikeway is a 5-mile (8.0 km) pedestrian and bicycle path that parallels State Route 237. The majority of the path is separated from vehicular traffic, however, two sections comprising a total of 1.5 miles (2.4 km) follow an on-street alignment adjacent the freeway. This bikeway serves as an important connector in the network of ...
Caesium-137 ( 137. 55Cs. ), cesium-137 (US), [7] or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission of uranium-238.
State Route 237. State Route 237 ( SR 237) is a primary state highway in the U.S. state of Virginia. The state highway runs 13.07 miles (21.03 km) from SR 236 in Fairfax east to U.S. Route 50 (US 50) in Arlington. SR 237 connects Fairfax and Arlington with Falls Church. Between Fairfax and Falls Church, the state highway mostly runs ...
Uranium-237 has a half-life of about 6.75 days. It decays into neptunium-237 by beta decay . It was discovered by Japanese physicist Yoshio Nishina in 1940, who in a near-miss discovery, inferred the creation of element 93, but was unable to isolate the then-unknown element or measure its decay properties.
