Ionization energy of Na and Mg
« on: November 29, 2005, 01:12:55 PM »
I had a question on my exam that asked which second ionization energy would be greater for Na or Mg

Mg:1s2 2s2 2p6 3s2   Zeff = 1.5
Na:1s2 2s2 2p6 3s1   Zeff =  1

Since the Zeff is lower in Na, will there be less energy required in Na?
Thanks

Will Zeff be the same after removing an electron?
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

Which sounds more familiar between Na2+ and Mg2+?
