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