Question

Using the periodic table and your knowledge of atomic structure. Compare the number of electrons in a Carbon-12 and Carbon-14 isotope. A. Carbon-12 has no electrons and Carbon-14 has 2 electrons B. Both have 6 electrons. C. Carbon-12 has 6 electrons and Carbon-14 has 8 electrons D. Carbon-12 has 12 electrons and Carbon-14 has 14 electrons

Answer 1

B. is answer
as isotopes have diff atomic mass but same atomic no
same atomic no = same proton no. =same electron no.

Answer 2

both have six electrons......

EXPLANATION:

C-12 and C-14 are atoms of the same element having same proton number and different nucleon number i.e they are isotopes of each other.....

since both are neutral i.e they r not ions so there is gain or loss of electrons....it means no of electrons in both the isotopes should be same.....i.e six electrons in each carbon isotope.......
