P - Phosphorus
The Third
If the valence electrons are being added to the 4f orbitals, that means the element is lanthanides or actinides which further proves that the element is a heavy element and a member of f -block.

the no of sigma bonds is equal to the no of hybrid orbitals in co-valent compounts. and the no of pi bonds equal to the pure orbitals eg: in ethylene for one carbon atom has 3 sigma bonds means that it has 3 hybrid orbitals (sp2), and it has one pi bond means that it has only one pure p orbital.
all elements in a period have the same amount of orbitals and if an element is in period 2 it has 2 orbitals if it is in period 3 it has 3 orbitals ..etc
Each and every element after Lithium has these orbitals.
P - Phosphorus
The maximum number of electrons in the 2p sublevel is 6. The p sublevel has three orbitals, each of which can take two electrons.
You would have to determine the electron configuration for atoms of a given element. Each s sublevel contains 1 orbital, each p sublevel contains 3 orbitals, each d sublevel contain 5 orbitals, and each f sublevel contains 7 orbitals.

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'.
Yes,It Is :)
Three completely filled orbitals.
