C14 is radioactive element because it on beta positive decay form nitrogen
shaili143:
how to understand that
there are 2 types of radioactive decay
one beta negative and other beta positive
in beta negative decay there is decrease in atomic number by 1
and in beta positive?
and in beta positive decay there is increase in atomic number by 1
so atomic no. 6 will become 7
how have you got atomic number of CH14
carbon has atomic no 6
please make it brailest answer
