Bohrium is a synthetic and radioactive element with an atomic number of 107. It is in the manganese group, also known as group 7. It was first created by a group of people in the Joint Institute for Nuclear Research in Russia. It is especially unstable, with its longest-lived isotope having a half-life of less than 12 minutes before decaying into another unstable element, Dubnium. It has similar behavior to its lighter homologue, rhenium.

Element Cattos
Element Cattos is a blog and web comic made by Lily Irie. It revolves around cat-like creatures that represent different elements of the periodic table, sometimes even compounds and isotopes. It has a game on itch.io, and it has a mobile port. It has been put on an indefinite hiatus due to the fanbase growing too quickly, and the pressure that comes with it.
