The correct reason why the noble gases are the least reactive elements is:
Their outer most energy levels are complete with 8 electrons.
This complete outer shell of electrons makes them stable and less likely to react with other elements.
Why are the noble gases the least reactive elements? (1 point)
O
They have the same number of electrons as protons.
They are the last elements in each row on the periodic table.
They are all radioactive.
