In December, the international body that governs the rules of naming chemicals added four new elements to the periodic table. In one swoop, the International Union for Pure and Applied Chemistry had finally completed the seventh row of the periodic table.
Yesterday (June 8), the groups that discovered those elements were invited to propose new names, which will undergo a public review before final acceptance. Japanese researchers proposed Nihonium (Nh) for element 113, named after the Japanese name for Japan. US and Russian researchers proposed Moscovium (Mc) for element 115, after Moscow; Tennessine (Ts) for element 117, after Tennessee, where one of the research labs is based; and Oganesson (Og) for element 118, after scientist Yuri Oganessian. The only other US state to have received this honor is California, with Californium (Cf).
Before they were proposed, the groups had to make themselves familiar to some strange rules that have been laid down for naming new elements. In brief, here are the rules: Names must not differ in different languages, and they can only be named after a place, a mythological character, a mineral or a property of the element, or a scientist. Many element names have their origins in Greek or Latin, but they also come from French, German, English, Persian, Swedish, Sanskrit, and other languages.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
