Question

Which atom (X) is indicated by the following configuration? X → [Ne] 3s2 3p3 (A) Nitrogen (B) Chlorine (C) Phosphorus (D) Sulphur

Tardigrade Admin · Accepted Answer

Given electronic configuration of X :[ Ne ] 3 s 2 3 p 3 where [Ne] is 1 s2 2 s2 2 p6 thus X is: 1 s2 2 s2 2 p6 3 s2 3 p3 Its an element with atomic number (2+2+6+2+3)=15 It is Phosphorus ( P )= X

Q. Which atom $(X)$ is indicated by the following configuration?
$X \to [N e] 3 s^{2} 3 p^{3}$

Nitrogen

Chlorine

Phosphorus

Sulphur

Given electronic configuration of $X : [N e] 3 s^{2} 3 p^{3}$
where $[N e]$ is $1 s^{2} 2 s^{2} 2 p^{6}$
thus $X$ is: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{3}$
Its an element with atomic number $(2 + 2 + 6 + 2 + 3) = 15$
It is Phosphorus $(P) = X$
