Titanium has an atomic number of 22. The following orbital notation for titanium is incorrect. Explain the error in terms of the rules for electron arrangements.

Titanium:

1s is filled. 2s is filled. 2p is filled. 3s is filled. 3p is filled. 3d is shown with five orbitals. Orbitals one through four have one electron each and the fifth orbital is empty.

1s(↑↓) 2s(↑↓) 2p(↑↓)(↑↓)(↑↓) 3s(↑↓) 3p(↑↓)(↑↓)(↑↓) 3d(↑)(↑)(↑)(↑)()

The e- in 3d orbital are wrong. After 3p, 4s orbital is a lower energy level. As lower energy orbitals are filled first, the orbital notation after 3p would be : 4s(↑↓) 3d (↑)(↑)
is that right?

anonymous · Answer

they skipped the 4s orbital

anonymous · Answer

it should be 3s 3p 4s 3d

anonymous · Answer

The reason for this is that the 4s orbital is lower in energy than the 3d orbital

ohh, gotcha, thank you!
