Textbook Question

Chapter 2, Problem 1TFQ

The number of neutrons in the nucleus is the atomic number of that element.

Expert Solution & Answer

To determine

Whether the given statement is true or false.

Answer to Problem 1TFQ

False.

Explanation of Solution

Given:

The given statement is:

An atomic number of an element is the count of neutrons in the nucleus of that element.

Calculation:

The atomic number of an element can be defined as the number of protons in an atom. The atomic weight or also called as the mass number of an element is equal to the number of protons and neutrons in an atom.

That is,

Atomic weight = Number of neutrons + Number of protons

Atomic weight = Number of neutrons + Atomic number

Number of neutrons = Atomic weight - Atomic number

Therefore, the atomic number of an element is not equal to the count of neutrons in the nucleus of that element.
