The element 118, previously known as eka-radon (eka being sanskrit for one) or ununoctium (one one eight element) was renamed in 2016 after the nuclear physicist Yuri Oganessian. It is the heavier analogue of Radon, thus, it is a noble gas. However, it is theorized that it would be a solid at the standard atmospheric pressure. Like its lighter analogues Radon and Xenon, it would be relatively easy (compared to Helium and Neon) to bond Oganesson to things like halogens and alkali metals.

Oganesson, in its most stable (known) form, has 118 protons, 176 neutrons, and 118 electrons. It is considered by some to be the last of the Periodic Table of Elements, however scientists are currently working on synthesis of elements 119, 120, 121, and 122.
Guy 1: Wow, thanks to Oganesson, the periodic table is finally complete!
Guy 2: But, scientists in Germany claim to have discovered Unbinilium. If their claims can be verified by another team, then that will be the start of a whole new row!
Guy 1: Ow, right in the OCD...

Get the oganesson mug.
An chemical element which is very radioactive.Any visible amount of it will be instantly vapourize.
Oganesson is the last element in the seventh period of the periodic table.

An element with a FLOOF LOT OF NEUTRONS.
Protons & electrons: 118
Neutrons: 176 THATS A LOT
Hydrogen: Oganesson, why do you keep on decaying so quick?
Oganesson: Bec-- (decays)
