Ne is the symbol representing an atom in the ground state with the most stable valence electron configuration

Answer: \(Ne\)

Explanation: The stable valence configuration is one in which the orbitals are completely filled as they are least reactive. Elements with partially filled valence shells are less stable and more reactive as they tend to gain or lose electrons to acquire stability.
