In the modern periodic table,elements are arranged in

Determine the position of the element in the periodic table for the following outer electronic configurations:
$(i)$ $ns^2 np^4$ where $n = 3$
$(ii)$ $(n-1)d^2 ns^2$ where $n = 4$
$(iii)$ $(n-2)f^7 (n-1)d^1 ns^2$ where $n = 6$

The number of elements in each of the long periods in the periodic table is

The $IUPAC$ nomenclature of an element with electronic configuration $[Rn] 5f^{14} 6d^{1} 7s^{2}$ is.

Match the following:

List-$I$ (Atomic number)	List-$II$ (Group number and Period number)
$A$. $56$	$I$. $9, 4$
$B$. $50$	$II$. $3, 6$
$C$. $27$	$III$. $14, 5$
$D$. $58$	$IV$. $2, 6$

What is the position of transition elements from $Sc$ to $Zn$ in the long form of the periodic table?
