Final answer:
The hypochlorite ion, ClO-, has one single bond between the chlorine and oxygen atoms, with three lone pairs on each atom to complete their octet.
Step-by-step explanation:
The student has asked about the number of bonds in ClO3, which I believe is a typo, and they are likely referring to the hypochlorite ion, ClO- (often written as OCl-). According to the information provided, hypochlorite has a total of 14 valence electrons, which are distributed between the oxygen and chlorine atoms. When we place a bonding pair of electrons between the oxygen and chlorine, we form a single bond, and with the remaining electrons, we put three lone pairs on each atom to fulfill the octet rule. Hence, the hypochlorite ion, ClO-, has one single bond between the chlorine and oxygen atoms.
