identify the neutral element represented by this excited-state electron configuration: 1s²2s²2p⁴3s¹

F

what is the ground state electron configuration of the neutral element represented by this excited-state electron configuration: 1s²2s²2p⁴3s¹

1s²2s²2p⁵

how many electrons does a Mn atom have in its 3d subshell

5

of the electrons in Mn’s 3d subshell, how many are unpaired

5

what element of lowest atomic number contains a complete d subshell in the ground state

Cu

what is a paramagnetic element?

a paramagnetic element has unpaired electrons, which causes them to be attracted to magnetic fields, and results in a non-zero net spin

what is a diamagnetic element?

a diamagnetic element has all paired electrons, resulting in a net zero spin
