O ELECTRONIC STRUCTURE AND CHEMICAL BONDING Predicting the single-bonded molecular compounds formed by... For each row in the table below, decide whether the pair of elements will form a molecular compound held together by covalent chemical bonds. If the elements will form a molecular compound, check the box and enter the chemical formula and name of the compound. (If the elements will form more than one molecular compound, use the compound with the fewest total number of atoms.) You may assume all chemical bonds are single bonds, not double or triple bonds. molecular compound element #1 element #2 element pair will form a molecular compound chemical formula name X ? ? carbon fluorine potassium oxygen hydrogen iodine O
