Question

how many neutrons are in the following isotope: * carbon - 14
your answer

what is the mass number of nitrogen if it has 8 neutrons *
your answer

carbon has three isotopes: *
carbon - 12
carbon - 13
carbon - 14
which isotope has more neutrons?
carbon - 12
carbon - 13

Explanation:

Step1: Recall carbon's atomic number

Carbon's atomic number is 6, which means it has 6 protons.

Step2: Calculate neutrons in Carbon - 14

The mass number of Carbon - 14 is 14. Using the formula $Neutrons=Mass\ number - Protons$, we have $14 - 6=8$.

Step3: Recall nitrogen's atomic number

Nitrogen's atomic number is 7, so it has 7 protons.

Step4: Calculate mass number of nitrogen with 8 neutrons

Using the formula $Mass\ number=Protons + Neutrons$, we get $7 + 8 = 15$.

Step5: Compare neutrons in carbon isotopes

For Carbon - 12: $12-6 = 6$ neutrons. For Carbon - 13: $13 - 6=7$ neutrons. For Carbon - 14: $14 - 6 = 8$ neutrons. So Carbon - 14 has the most neutrons.

Answer:

8
15
Carbon - 14
