What exactly are the trends in the periodic table? Is this right:

(a) go more right (ionization energy increases)
(b) go more down atomic radius increases

What are the trends for second ionization energy, ionic radius, ionization energy? If you are given a electron configuration how do you use this in relation to the periodic trends?

Thanks a lot :smile:

Yes, (a) and (b) seem correct. Second ionization energy tends to be even higher than the first, but it is minimum in IIA group (aka earth alkali metals), since they prefer to be 2+ in their solutions. Other ionization energies can be treated similarly, if the stable ion has the configuration n+, then its nth ionization energy will be minimal among the period.

Hope this helps as a first attempt.
