Question

how many e.s are present in ground state of fe2+(at. no fe=26)​

Answer 1

Answer:

Explanation:

As we know the atomic number of Fe is 26 . As fe2 + has 24 electrons 1s2,2s2,2p6,3s2,3p6,4s2and 3d4 in these d-orbital has 4 electrons to fill when we fill electrons in D-orbital there will be 4 electrons will be unpaired .

No of unpaired electrons are 4

hope it helps

if so please mark me brainliest!!! tyvm!!!

Answer 2

Answer:

Fe has configuration of 4s2 ,3d6 after losing of 2 electrons it become Fe2+ and have only 3d6 configuration having 4 unpaired electrons and one paired electron . There are 4 unpaired electrons in d subshell in Fe+2
