Let’s solve this step by step.
We are looking at a diagram of an atom, called “Matterville,” and we need to label the parts based on what they do — specifically, how many electrons each part can hold or what it contains.
The diagram has:
- A central dark circle (the nucleus)
- Three rings around it (electron shells)
Arrows point to different parts with descriptions:
1. Arrow pointing to the center → “Contains protons & neutrons”
→ That’s the
nucleus. In atoms, protons and neutrons live in the center.
2. Arrow pointing to the first ring (closest to center) → “Can hold up to 2 electrons”
→ This is the
first electron shell (or energy level). The innermost shell holds max 2 electrons.
3. Arrow pointing to the second ring → “Can hold up to 8 electrons”
→ This is the
second electron shell. It can hold up to 8 electrons.
4. Arrow pointing to the third ring → “Can hold up to 18 electrons”
→ This is the
third electron shell. It can hold up to 18 electrons.
So, labeling from inside out:
- Center: Nucleus
- First ring: Shell 1 (holds 2)
- Second ring: Shell 2 (holds 8)
- Third ring: Shell 3 (holds 18)
This matches basic atomic structure taught in middle school science.
Final Answer:
- Center (dark circle): Nucleus
- Innermost ring: First electron shell (holds up to 2 electrons)
- Middle ring: Second electron shell (holds up to 8 electrons)
- Outermost ring: Third electron shell (holds up to 18 electrons)
