The name 'ununpentium' follows the IUPAC systematic element naming convention, but its meaning is not transparent to learners without specific chemical knowledge.
Etymology
The word ununpentium was a temporary name used by scientists, made from number parts: un- 'one', un- 'one', pent- 'five', and the ending -ium 'metal'. So the name showed the element's number was 115, and later it was officially named moscovium.
