Given information

Here the given isotope of phosphorous is:

We have to find out the number of protons and neutrons present in the isotope.

Step-by-step explanation

Step 1.

The number of protons or electrons present in an atom represents the atomic number. Then the number of protons or electrons of an element can be determined from its atomic number (Z).

 

The mass number (A) is subtracted from the number of protons which represents the atomic number(Z) to calculate the number of neutrons (N). Then,

 

 

  

Here in the given isotope , the atomic number is and the mass number is

Since the atomic number gives the number of protons, the isotope consists of  protons and the number of neutrons is:

         

         

Thus the isotope consists of protons and neutrons.
