New element ?
Elements are defined by the number of protons. We have found all the naturally occurring ones & synthesised others so we have a complete list from 1 to 118. All the elements over 109 have half lives you need a stopwatch to measure, and the higher you go, the less stable it is. These are generally made in particle acellerators.
There are no naturally occurring new elements left to discover
PS. appy polly loggies for plagiarising, but I could not think of a better response.
