Problem: Understanding Electricity and Atomic Structure

The worksheet asks you to label diagrams, explain phenomena related to electricity, and answer questions about atomic structure. Below is a detailed solution with explanations for each part.

---

1. Label the parts of the atom and their charges.

#### Diagram:
- The diagram shows an atom with a nucleus and orbiting electrons.
- Labeling:
- Nucleus: Contains protons and neutrons.
- Protons: Positively charged particles in the nucleus.
- Neutrons: Neutral (no charge) particles in the nucleus.
- Electrons: Negatively charged particles orbiting the nucleus.

#### Charges:
- Protons: +1 charge
- Neutrons: 0 charge
- Electrons: -1 charge

2. Label and explain what is happening with the above two atoms.

#### Diagram:
- Two atoms are shown, one with a missing electron and another with an extra electron.
- An arrow indicates the movement of an electron from one atom to the other.

#### Explanation:
- The atom on the left has lost an electron, making it positively charged (since it now has more protons than electrons).
- The atom on the right has gained an electron, making it negatively charged (since it now has more electrons than protons).
- This process demonstrates the transfer of electrons between atoms, which is fundamental to electrical conductivity and chemical bonding.

#### Labeling:
- Atom on the left: "Positively charged atom (missing an electron)."
- Atom on the right: "Negatively charged atom (gained an electron)."
- Arrow: "Electron transfer."

3. This diagram shows _______.

#### Diagram:
- A series of negative charges (-) moving through a conductor.

#### Explanation:
- This diagram represents the flow of electrons in a conductor. Electrons are negatively charged particles that move through a material when an electric current is applied.
- The direction of the arrow indicates the direction of electron flow.

#### Answer:
- This diagram shows the flow of electrons in a conductor.

4. All matter is made of _______.

#### Explanation:
- All matter is composed of atoms, which are the basic building blocks of matter.

#### Answer:
- All matter is made of atoms.

5. Small particles in an atom have an _______ charge.

#### Explanation:
- The small particles in an atom are protons, neutrons, and electrons. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge.

#### Answer:
- Small particles in an atom have an electric charge.

---

6. Electrons have a _______ charge.

#### Explanation:
- Electrons are negatively charged particles.

#### Answer:
- Electrons have a negative charge.

---

7. Protons have a _______ charge.

#### Explanation:
- Protons are positively charged particles.

#### Answer:
- Protons have a positive charge.

---

8. Inner orbiting electrons are called _______.

#### Explanation:
- Inner orbiting electrons are tightly bound to the nucleus and are not easily removed. These are called core electrons or inner-shell electrons.

#### Answer:
- Inner orbiting electrons are called core electrons.

---

9. Outer orbiting electrons are called _______.

#### Explanation:
- Outer orbiting electrons are loosely bound and can be transferred between atoms. These are called valence electrons.

#### Answer:
- Outer orbiting electrons are called valence electrons.

---

10. We use wires to produce an orderly _______.

#### Explanation:
- Wires are used to create a path for the flow of electrons, which is known as an electric current. The orderly movement of electrons in a wire is what produces electricity.

#### Answer:
- We use wires to produce an orderly electric current.
