Write electron configuration for Te2-?
I am having the hardest time finding the configuration for Te2-. I need it written out the long way. I have entered 1s^22s^22p^63s^23p^63d^104s^24p^64d^105s…
and got wrong. Can someone please help!
click on the orbitals tab
look at the filling pattern for Te
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p4
add 2 electrons to make it -2
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 .
The order is not 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, ...
But: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p , 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p
