Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactiveNeon has an even number of electrons so it does not need to form bondsNeon has the same number of electrons and protons so it is unreactiveNeon is a noble gasNeon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electronsQuestion 16 of 16 Loading...
