Flerovium/Symbol
Since this podcast was first published, the name of this element has been ratified as flerovium (symbol Fl) by the International Union of Pure and Applied Chemistry (Iupac). The name recognises Russian physicist Georgiy Flerov, who discovered the spontaneous fission of uranium.
Who created Nihonium?

How did flerovium get its name?
Word origin: Flerovium is named for Russian physicist Georgy Flyorov, founder of the Joint Institute of Nuclear Research in Dubna, Russia, where the element was discovered.
What is flerovium made from?
plutonium
To make flerovium, atoms of plutonium (Element 94) are bombarded with ions of calcium (Element 20) contained in a beam.
How was flerovium discovered?
Flerovium was first produced by scientists working at the Joint Institute for Nuclear Research in Dubna, Russia in 1998. They bombarded atoms of plutonium with ions of calcium. This produced a single atom of flerovium-289, an isotope with a half-life of about 21 seconds.
Is Oganesson a metal?
Oganesson is a radioactive, artificially produced element about which little is known. It is expected to be a gas and is classified as a non-metal. The element, No. 118 on the Periodic Table of Elements, had previously been designated ununoctium, a placeholder name that means one-one-eight in Latin.
Is oganesson element heaviest?
Oganesson, named for Russian physicist Yuri Oganessian (SN: 1/21/17, p. 16), is the heaviest element currently on the periodic table, weighing in with a huge atomic mass of about 300. Only a few atoms of the synthetic element have ever been created, each of which survived for less than a millisecond.
What is the story of the johatsu?
This is the strange story of Japan’s evaporated people and the town they call home. One very unusual cultural trend in Japan in recent times has been that of what are called the johatsu, or roughly translated to the rather creepy sounding “evaporated people.”
Who are the evaporated people?
The Evaporated People, known as the johatsu in Japan, are the tens of thousands that disappear without a trace every year. They are those that leave their jobs, studies or families often driven by shame, hopelessness or personal disappointment.
Why is Jouhatsu such a taboo in Japan?
During the 1990s, the Japanese economy crashed, leading to a spike in jouhatsu and suicide as many salarymen lost their jobs and/or accumulated debt. In Japan, the topic of jouhatsu is taboo in regular conversation, like the topic of suicide. It has been estimated that one hundred thousand Japanese people disappear annually.
Why do people become Jouhatsu?
The shame of job loss, divorce, and even failing an exam can also motivate people to disappear. In some cases, becoming jouhatsu is a way to just have a fresh start. When they disappear, they can abandon their former residences, jobs, families, names, and even appearances.
