Question

What is the mass number of Carbon–12, which has 6 protons and 6 neutrons?6181224

Answer 1

INFORMATION:

We have the following options:

- 6

- 18

- 12

- 24

And we must select the one which is the mass number of Carbon–12 with 6 protons and 6 neutrons

STEP BY STEP EXPLANATION:

To select the correct one, we must know that:

So, we can calculate the mass number as

$mass\text{ }number=protons+neutrons$

In our case, there are 6 protons and 6 neutrons.

So,

$mass\text{ }number=6+6=12$

Finally, the mass number of Carbon–12, which has 6 protons and 6 neutrons is 12

ANSWER:

12
