Select the false statement below : fe2+ is more paramagnetic (has more unpaired electrons) than fe3+ fe3+ is isoelectronic with mn2+ fe has 2 outer electrons, 8 valence electrons, and 18 core electrons fe3+ is predicted to be a stronger potential oxidizing agent (can be reduced more) than fe2+ none of these ions (fe2+, fe3+, mn2+) have any electrons in the 4s subshell

hey there!:

1) none of these ions ( Fe²⁺ , Fe³⁺ , Mn²⁺ 0 have any electrons in the 4s subshell .  ( TRUE )

2) Fe²⁺ is more paramagnetic ( has more unpaired electrons ) than Fe³⁺.

( FALSE )  explanation :

* Fe²⁺ has no free electrons and is diamagnetic

* Fe³⁺ has one unpaired electron and is paramagnetic

3) Fe³⁺ is isoeletronic with Mn²⁺ . ( TRUE )

4) Fe has 2 outer electrons , 8 valence electrons , and 18 core eletrons. (TRUE )

electron configuration  Fe = 1s², 2s², 2p⁶, 3s² , 3p⁶, 4s² , 3d⁶ or :

[Ar] = 4s²  , 3d⁶

5) Fe³⁺ is predicted to be a stronger potencial oxidizing agent  ( can be reduced more ) than Fe²⁺   ( TRUE )

Hope this helps!

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
