answer is c

According to the key ans is D that is the chemical properties but isotopes hv same atomic numb. N the chemical properties depends upon at.no. since they hv same at no so how can they hv differentchemical properties...

UNSA said:
C SHOULD BE RIGHT ANSWER
kiran said:
ans c is true
sapna said:
C SHOULD BE RIT ANS
as isotopes differ in atomic mass not atomic no
and atomic no depnds on chemical properties atomic mass depnds on physical properties
aliraza said:
isotopes differ in properties depend on mass because istopes consist of different atomic masses
ajab khan said:
isotopes differ in atomic mass # not in atomic number...
