In which group of the Periodic Table will you put the elements with electronic configuration [He] 2s² 2p⁶?

Correct option is C

The correct answer is (c) 18
The electronic configuration [He]2s²2p⁶ corresponds to the element Neon (Ne), which has a total of 10 electrons. This electronic configuration completes both the s and p orbitals of the second energy level, making Neon a noble gas. Noble gases are located in Group 18 of the Periodic Table. This group is characterized by elements that have their outermost energy levels fully filled, which makes them highly stable and inert under normal conditions.
