New elements added to chemistry's periodic tableTwo new elements have been added to the periodic table after a three-year review by the governing bodies of chemistry and physics.The elements are currently unnamed, but they are both highly radioactive and exist for less than a second before decaying into lighter atoms.
BBCShould they really be included if they're so unstable they don't exist for more than a few seconds? Just doesn't seem right to me.
There are many elements on the periodic table that only exist for a limited time before decaying to another element or isotope. If we consider lifespan of an element to be a primary dictator of inclusion in the periodic timetable - where do we draw the line when it comes to lifespan ?
If it happens in nature, maybe add it but if it's totally man made, put as a side dish.
