Why can phosphorus not bond to carbon?

According to the theory, there could be no triple bonding between carbon and phosphorus because their electron orbitals could not fit together, nor should it be possible for a carbon atom to be replaced by a phosphorus atom and still retain the same structure.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
