How many elements have been "properly" named so far by the IUPAC?

Question

Also, how many have been discovered but need to be named? Please answer! Thank you!

Answer 1

111 elements. The transactinide elements are:

#104 = Rutherfordium (Rf)
#105 = Dubnium (Db)
#106 = Seaborgium (Sg)
#107 = Bohrium (Bh)
#108 = Hassium (Hs)
#109 = Meitnerium (Mt)
#110 = Darmstadtium (Ds)
#111 = Roentgenium (Rg)

The last one was named last year.

Answer 2

actually International Union Of Pure And Applied Chemistry (IUPAC) has named 109 elements correctly and they are from 1 to 109.
