Which of the following elements belongs to the $1^{st}$ group and $5^{th}$ period of the periodic table?

If the $IUPAC$ name of an element is $Unununnium$,then the element belongs to the $n^{th}$ group of the periodic table. The value of $n$ is . . . . . .

$Zn$ belongs to which group in the periodic table?

Identify the incorrect match from the following table of elements with atomic number $Z > 100$ and their $IUPAC$ names:

Temporary Systematic Name	$IUPAC$ Official Name
$a$. Unnilunium $(101)$	$i$. Nobelium $(No)$
$b$. Unniltrium $(103)$	$ii$. Lawrencium $(Lr)$
$c$. Unnilhexium $(106)$	$iii$. Seaborgium $(Sg)$
$d$. Ununnilium $(110)$	$iv$. Darmstadtium $(Ds)$

Assign the position of the element having outer electronic configuration in the periodic table:
$(i)$ $ns^{2} np^{4}$ for $n=3$
$(ii)$ $(n-1)d^{2} ns^{2}$ for $n=4$
$(iii)$ $(n-2)f^{7} (n-1)d^{1} ns^{2}$ for $n=6$

Derive the $IUPAC$ name of the element having atomic number $106$.
