Element "E" belongs to the period 4 and group 16 of the periodic table. The valence shell electron configuration of the element, which is just above ‘E’ in the group is (A) 3 s2 ⋅ 3 p4 (B) 3 d 10 ⋅ 4 s 2 ⋅ 4 p 4 (C) 4 d 10 ⋅ 5 s 2, 5 p 4 (D) 2 s 2, p 4

Q. Element " $E$ " belongs to the period $4$ and group $16$ of the periodic table. The valence shell electron configuration of the element, which is just above ‘ $E$ ’ in the group is

$3 s^{2} \cdot 3 p^{4}$

$3 d^{10} \cdot 4 s^{2} \cdot 4 p^{4}$

$4 d^{10} \cdot 5 s^{2}, 5 p^{4}$

$2 s^{2}, p 4$

$E \Rightarrow [A r] 3 d^{10} 4 s^{2} 4 p^{4}$
Element above $E \Rightarrow [N e] 3 s^{2} 3 p^{4}$
