1. Why is ther a large jump in ionization energy between the second and third ionization energies for magnesium?
2. Explain why noble gases are inert and do not form ions?
thanks!

1. after Mg is ionized a second time, it has an octet, and doesnt want to give up any more electrons
thats why the third ionization energy is freakin high
2. noble gases are inert because they have filled valence (outer) electron levels
they all have an octet except helium (because it has only two electrons), and this means their valence level is filled

2) a noble gas is inert because its outermost shell is completely full. However given enough energy you can knock out electrons from even a noble gas to create an ionized version.

2. Because they have eight electrons at the outer shell, which is the strongest form of the electrons shell
