How do the electron configurations within the same group of elements compare? Why are the noble gases relatively unreactive?

Answer:

1.) Electron configurations within the same group of elements have the same valence electron configurations.

2.) Noble gases are relatively unreactive because they have a completely filled outer/valence shell. Since they are already in the most stable electronic configuration, they do not easily gain or lose electrons. This limits their ability to participate in chemical reactions.
