What is the oldest element in the universe?
The first elements — hydrogen and helium — couldn’t form until the universe had cooled enough to allow their nuclei to capture electrons (right), about 380,000 years after the Big Bang.
Which element is the most expensive?
As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium . It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium.
What is the newest element found?
