Let's solve the problem step by step.
Understanding the Diagram:
The image shows a simplified model of an atom, with:
- A central cluster of particles (blue and red spheres).
- Green spheres orbiting in circular paths around the center.
- Two concentric circles representing energy levels or orbits.
We are given the following words to fill in the boxes:
- neutrons
- protons
- electrons
- electron shells
- nucleus
---
Step 1: Identify the Central Part
The central cluster (blue and red spheres) is the
nucleus.
- The blue spheres with "+" signs are
protons (positively charged).
- The red spheres (no charge symbol) are
neutrons (neutral).
So, the
nucleus contains
protons and
neutrons.
---
Step 2: Identify the Orbiting Particles
The green spheres with "−" signs are
electrons, which are negatively charged and orbit the nucleus.
They move in
electron shells (also called energy levels), which are the circular paths shown.
---
Step 3: Match Labels to Boxes
Looking at the diagram:
1. The
central cluster is labeled with a box pointing to it — this should be
nucleus.
- From the nucleus, two smaller boxes branch out — these must be
protons and
neutrons (since they make up the nucleus).
2. The
outer circles (the rings) represent
electron shells.
- The
green dots on those rings are
electrons.
So:
- The large box pointing to the outer rings →
electron shells
- The small box pointing to the green dots →
electrons
---
Final Answer:
Label the boxes as follows:
-
Top box (pointing to nucleus): nucleus
-
Two boxes branching from it: protons and
neutrons
-
Bottom box (pointing to the outer rings): electron shells
-
Box pointing to the green dots: electrons

Note: The actual positions of the labels depend on the lines in the diagram. Based on typical layout:
>
> - The box connected directly to the center is
nucleus.
> - The two boxes branching from it are
protons and
neutrons.
> - The box pointing to the circular paths is
electron shells.
> - The box pointing to the green dots (electrons) is
electrons.

✔ Answer Summary:
-
Center box: nucleus
-
Branches from nucleus: protons, neutrons
-
Outer ring box: electron shells
-
Green dots box: electrons
This correctly identifies all parts of the atom.
