Periodic Re Mo Notebook
In a Periodic Table (Russian chemist Dmitri Mendeleev circa 1869), the elements are arranged in columns and rows according to increasing atomic number.
Rhenium is a very dense, high-melting, silver-white metal used in alloys with tungsten; delivering improved ductility and high-temperature strength for use in electrical contacts, electronic filaments, thermocouples and photographic flash lamps.
Molybdenum is a hard, malleable, ductile, high-melting, silver-white metal with a body-centered cubic crystalline structure. Because it retains its strength and structure at very high temperatures, it has found use in certain critical rocket and missile parts.
Serendipitously, Rhenium (symbol Re) happens to form a superconductive alloy with Molybdenum (symbol Mo)!
Some things are clearly meant to be.
