If you found carbon 13 atom, you would know that
bearhunter [10]
The Options are as follow,

<span>a. it has 13 protons                  c. it has 13 neutrons                      </span>

<span>b. it has 13 electrons               d. it has 7 neutrons</span>


Answer:

             Option-d is the correct answer.


Explanation:

             As we know that C-13 has a atomic mass of 13. Also, atomic mass is given as,


<span>                 Atomic Mass  =  # of Protons  +  # of Neutrons   --- (1)</span>


Since;

          Atomic Mass  =  13

And,

          # of protons  =  6 (as number of protons  =  atomic number)


Putting values in equation 1,


                               13  =  6  -  # of Neutrons


Solving for Number of Neutrons,


                               # of Neutrons  =  13  -  6


                               # of Neutrons  =  7
