Question

what is the mass number of a carbon isotope with 10 neutrons

Answer 1

Answer:

16 because carbon atom having usual 6 neutron have a mass number of 12 and that with 7 neutron has mass number of 13

Answer 2

A carbon atom with 10 neutrons would have a mass number of 16.
On the periodic table, carbon has an atomic number of 6 which indicates the amount of protons in the atom. Since atomic mass is the result of adding the amount of protons and neutrons in an atom together, we get that 6+10=16 and that 16 is the atomic mass.
