The Correct Option is A
Solution and Explanation
The correct answer is (A) : 3s2, 3p4
Element E is Selenium
The element which is just above ‘E’ in periodic table is sulphur, its electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p4.
\(E⇒[Ar]^3d^10^4s^24p^4\)
Element above \(E⇒[Ne]3s^23p^4\)

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
