Why is it that not 2 sigma bonds, and 3 pi bonds are formed in N2?

sigma bond is overlap of orbitals across the nuclear axis, that can only happen once (because it can only be one place). but you can form several pi bonds as they exist above and below the axis and there's several of those based on how you look at it. does that make sense?

In a N atom the p-orbitals are all at 90 degrees to each other, if you take some pens and arrange them like this, basically make a + with 2 pens and have the 3 pen sticking out of the +, then do the same with another 3 pens - then bring them together, for a sigma bond you need complete full on overlap - so only possible to do this with one pair of pens, the other will only do sideways overlap - that is a pi bond
