Question 1 Report

The nucleon number and the proton number of a neutral atom of an element are 238 and 92 respectively. What is the number of neutrons in the atom?
Answer Details
The number of neutrons in an atom is calculated by subtracting the number of protons from the nucleon number. In this case, the nucleon number is given as 238 and the number of protons is given as 92. Therefore, the number of neutrons is calculated as follows: Number of neutrons = Nucleon number - Proton number Number of neutrons = 238 - 92 Number of neutrons = 146 So, the answer is 146. Option (c) is the correct answer.
