Chapter 3: Problem 30

Calculate the number of neutrons of the atom whose atomic number is 42 and whose mass number is 96.

Short Answer

Expert verified
The number of neutrons in the atom is 54.

Step by step solution

01

Identify the atomic and mass numbers from the problem

The atomic number (number of protons) given is 42 and the mass number (total number of protons and neutrons) is 96.
02

Perform subtraction

Subtract the atomic number from the mass number. This will give the number of neutrons in the atom. So, Number of neutrons = Mass Number - Atomic Number = 96 - 42.
03

Obtain the Result

Now subtract 42 from 96. The result will be 54. Therefore, the number of neutrons in the atom is 54.
