A triple bond<span> is one </span>sigma<span> and two </span>pi bonds<span>. A </span>sigma bond<span> is your basic head-on covalent </span>bond<span>, with the </span>bond<span> in line with the </span>bonding<span> orbitals. You can only ever have one </span>sigma bond between<span> any two atoms. A </span>pi bond<span> is a covalent </span>bond between<span> orbitals perpendicular to the </span>bond<span> direction, usually p-orbitals (nevers)</span>
