what is the best thing to do when your super bored?

Answer:

Fe has 2 s electrons and 6 d electronsIt easily loses the 2 s electrons to yield Fe^2+Since the d orbitals can hold 10 e, 5 e constitute a half filled set of d orbitals, which is very stableSo Fe^2+ easily oxidizes to Fe^3+ by losing the 6th d electronMn, the element just before Fe, already has a half filled set of d orbitals, so it is inclined to lose only the 2 s electrons, to yield Mn^2+ Aluminum has 2 s electrons ans 1 p electronThe s orbitals are spherical, but the p orbital is elongated and protrudes farther from the atomit is more susceptable to interaction (or removal) than the s electronsAlso the 2 s electrons constitute a filled orbital set, which is stableYou will notice this same trend with the element pairs: Zn/Ga, Cd/In, and Hg/TlThese have closed s and d orbitals, followed by a single p electron.
