- In the molecule carbon tetrachloride, the electrons in each C-Cl sigma bond would be: closer to the chlorine atom because chlorine is more electronegative than carbon. located directly between the carbon and chlorine atoms. 13 closer to the carbon atom because carbon is less electronegative than chlorine closer to the carbon atom because carbon has the larger radius and has a greater gravitational pull.arrow_forwardHydrogen is in Group 1 of the periodic table. Which kind of bond would form between two hydrogens? O An ionic bond would form because both atoms are nonmetals. A covalent bond would form because the electron would be shared so both hydrogens have a fullI, stable shell. An ionic bond would form because one hydrogen would transfer its valence electron to the other hydroger make a full shell. O A metallic bond would form because both atoms are metals.
