Among the following the number of element showing only one non zero oxidationstate is O,CI,F,N ,P,Sn,TI,Na,Ti

Among the following the number of element showing only one non zero ox

1.	Among the following the number of element showing only one non zero oxidationstate is O,CI,F,N ,P,Sn,TI,Na,Ti
Answer» Solution :Non zero oxidation STATE of O are -1 -2 that of CI are -1 ,+1,+5 and +7 that of F is -1 that of P are -3 ,-2 +1,+3 and 5 that of Na is +1 and that of Ti is +2 , +3 and +4 Thus onlyF and Na can exist in ONE zero oxidation state
