An atom whose valence electrons conform to the octet rule is:
a) more likely to form covalent bonds b) more likely to form ionic bonds c) more likely to form hydrogen bonds d) more likely to become a free radical e) less likely to form any bond with another atom

less likely to form any bond with another atom

Explanation:

The reason for chemical combination is to enable the combining atoms attain noble gas configuration, that is, to have eight electron a around the outermost shell as specified by the octet rule. However for atoms such as noble gases that already have eight electrons around their outermost shell, there is a reluctance towards participation in chemical combination since the outermost shell already contains eight electrons as required by the octet rule.
