In the instance of carbon monoxide (CO), how is it that it has a triple bond connecting the two and a lone pair on each side when carbon only has 4 valence electrons and oxygen 6???? Are we able to just move electrons around like that or is there another reason? I know we learned about coordinate covalent bonds, but how are we supposed to know when they apply? Or do they always apply whenever convenient?

CO has 10 valence electrons in total. A triple bond would be 6 electrons and a lone pair on both the C and the O would add another 4, making 10 total while also fulfilling the octet rule for both.
