On the nonexistence of trivalent carbon
WebIt is not trivalent. Carbon has the capacity to form 4 bonds. See CH4, methane, as a prime example. It is tetravalent, if you want to use the Greek prefixes. C is a non metal … WebTrivalent definition: Triple. If we assume that a certain minimum electric charge must be brought into contact with a group of colloid particles to produce coagulation, twice as many univalent ions must collect to produce the same effect as a number of divalent ions, and three times as many as an effective number of trivalent ions.
