What element has the same number of electron orbitals as the element Sodium?

The element magnesium (Mg) has the same number of electron orbitals as sodium (Na).

Six1) , to be exact. The only orbital difference between the both is that sodium has one unpaired electron orbital whereas all the six orbitals of magnesium are paired.

Added:

1s2, 2s2, [2px22py22pz2], and finally 3s1 or 3s2 (for Na or Mg respectively)

1) Actually the three [2px22py22pz2] are sub-orbitals of the (one) 2p6-orbital.

The answer then would have been four in stead of 'Six'.
