Question
In response to a question, a student stated that in an atom, the number of protons is greater than the number of neutrons, which in turn is greater than the number of electrons. Do you agree with the statement? Justify your answer.
Solution
The given statement is not correct. As the number of protons is never greater than the number of neutrons. A number of neutrons can be equal to or greater than a number of protons but a number of protons are equal to a number of electrons for an atom since it is neutral.
