"If you could ever hold it, Dubnium would likely feel like a heavy, silvery-grey metal, but good luck with that!"
Did You Know?
You won't find Dubnium naturally anywhere on Earth – it's 100% human-made, cooked up in super-powerful particle accelerators!
Clocking in at atomic number 105, Dubnium is a 'superheavy' element, meaning it's packed with a massive number of protons and neutrons in its nucleus.
Its name isn't random! It honors Dubna, Russia, home to the Joint Institute for Nuclear Research (JINR), where scientists first crafted this elusive element.
Getting your hands on Dubnium is impossible. Scientists only create a few atoms at a time, making it one of the rarest substances ever known!
