Answer
In a molecule of nitrogen (N₂), there is one sigma bond formed between the two nitrogen atoms. This bond results from the head-on overlap of the atomic orbitals.

Answer
Additionally, in the nitrogen molecule, there are two pi bonds. These are formed by the side-to-side overlap of the unhybridized p orbitals on each nitrogen atom.
