Considering the periodic trends, which property explains why noble gases are chemically inert under standard conditions?
Completely filled valence shell
Noble gases have a completely filled valence shell, making them chemically stable and largely unreactive under standard conditions.
High electronegativity, low ionization energy and high atomic mass do not correctly explain the chemical inertness of noble gases.
Hence, 'Completely filled valence shell' is the correct answer.
