(i) Ionization energy generally increases down the group
(ii) Fe2+( the 2+ is in superscript form) has an electronic configuration of 1s^2, 2s^2, 2p^6, 3s ^2, 3p^6, 3d^4, 4s^2

Carol P, it's Fe2+, not Fe.in other words, the Fe has two electrons removed.

Ionization energy generally increases UP the group because the atoms have fewer protons pulling on the electrons. F is the most electronegative element on the periodic table.
Iron would not be 3d^4 4s^2 because it has 6 d electrons. It is therefore 3d^6 4s^2.

Quran and authenticated Hadiths do no longer contradict each and each others. in spite of the indisputable fact that, no longer each thing in Hadiths is in Quran. as an occasion, the Quran did no longer let us know to clip our nails, pluck our armpits hair, shave the pubic hair, etc etc.. however the Hadith did. The Quran in certainty stated "God is appealing and He loves attractiveness"
