Given information

Here the number of neutrons present in the plutonium isotope is:

Number of neutrons      

We have to determine the isotopic symbol of plutonium.

Step-by-step explanation

Step 1.

The isotopic symbol of an element can be represented in the form (X-A), where 'X' represents the chemical element and 'A' indicates the mass number.

Here the atomic number of plutonium is and the number of neutrons is and we have to find out the mass number of plutonium to represent the isotopic symbol.

The sum of atomic number(Z) and neutrons (N) of an atom is called the mass number (A) and it can be shown as:

    

Hence the mass number of plutonium with  neutrons is:

 

 

Thus the isotopic symbol of plutonium with neutrons is represented as .
