Problem 23a

Given information

Here the given isotope of nitrogen is:

Step-by-step explanation

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

The number of neutrons (N) in an atom can be obtained by subtracting the mass number (A) from the number of protons which indicates its atomic number(Z).

Then,

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

Thus the isotope consists of the same number of protons and neutrons.
