Question

Which of the following subshells has the LOWEST energy?

A ground-state atom of manganese has ________ unpaired electrons and is ________.

The representative elements are those with unfilled energy levels in which the "last electron" was added to

f orbital

Which element has the following ground-state electron configuration?

1s22s22p63s2

3d 4d 4p 5p

A ground-state atom of manganese has ________ unpaired electrons and is ________.

0, diamagnetic 2, diamagnetic 3, paramagnetic 5, paramagnetic 7, paramagnetic

The representative elements are those with unfilled energy levels in which the "last electron" was added to

s orbital s or p orbital d orbital p or d orbital

f orbital

Which element has the following ground-state electron configuration?

1s22s22p63s2

Al Si Ne Na Mg

1. 3d has lowest energy

2. The ground state electron configuration of ground state gaseous neutral manganese is [Ar].3d5.4s2

unpaired electron = 5 and paramagnetic

3. The representative elements add the electrons in the s or p orbitals.

4. 2+2+6+2 = 12

element will be Mg
