Hello Dear,

◆ Answer -

IUPAC name => Unquadennium

Symbol => Uqe

◆ Explanation -

For an element with atomic number 149, IUPAC name is derived as -

1 => un => u

4 => quad => q

9 => enn => e

Now, for this element,

IUPAC name => Un + quad + enn => Unquadennium

Symbol => U + q + e => Uqe

Hence, for element with atomic number 149, IUPAC name is Unquadennium and symbol would be Uqe.

Best luck dear. Hope this helps you...
