Neutron Examples in Chemistry
Start with the recap, study the fully worked examples, then use the practice problems to check your understanding of Neutron.
This page combines explanation, solved examples, and follow-up practice so you can move from recognition to confident problem-solving in Chemistry.
Concept Recap
A neutral subatomic particle found in the nucleus of an atom that has no electric charge but contributes to the atom's mass.
The glue that helps hold the nucleus together without adding charge.

- Read the first worked example with the solution open so the structure is clear.
- Try the practice problems before revealing each solution.
- Use the related concepts and background knowledge badges if you feel stuck.
What to Focus On
Core idea: Different numbers of neutrons create isotopes of the same element.
Common stuck point: Changing the neutron count changes the isotope but not the element — the proton count is what defines the element.
Worked Examples
Example 1
easySolution
- 1 Recall that the mass number A equals the total number of protons plus neutrons: A = Z + N.
- 2 Rearrange to find the neutron count: N = A - Z.
- 3 Substitute: N = 23 - 11 = 12 neutrons.
