Science is full of discoveries every day, do you think there are still unknown elements that we need to discover?

Below!

Explanation:

almost every day we find new species and new animals and new insects and more!but finding a new element is very rare the last new element that has ever been found was in 1939... Crazy right? Its crazy that there are no new elements discovered. so I think there will be a few more elements that would be discovered but it'll be very hard to find them.

If this answer helps please give brainily!
