What is the formula of a solid containing carbon that is a) molecular b)ionic c) network covalent d) metallic
for these arent there more than one right answers?
Describe the structural units in a) NaI b) N2 c) KO2 d) Au
The answer to your first question is, yes, probably there is more than one right answer.
NaI is ionic. N2 is covalent, KO2 is ionic and covalent (ionic between the K and O2 bond and covalent between the O2 bond). Look up gold on the periodic table to determine the structure. Its a metallic bond.
