Let’s go through each part of the worksheet step by step to understand and answer correctly.

---

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

An atom has three main parts:

- Protons → found in the nucleus, have a positive (+) charge.
- Neutrons → also in the nucleus, have no charge (neutral).
- Electrons → orbit around the nucleus, have a negative (-) charge.

In the diagram on the left:
- The center circle with “+” signs = protons
- The center circle with “0” or blank = neutrons (sometimes not shown with charge)
- The small circles on the rings = electrons

In the right diagram (two atoms):
- Top atom: nucleus has protons and neutrons; outer ring has electrons.
- Bottom atom: same, but one electron is moving away (shown by dotted arrow).

So label:
- Nucleus (center) → contains protons (+) and neutrons (0)
- Electron shells (rings) → contain electrons (-)

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

The top atom is neutral (equal protons and electrons).
The bottom atom is losing an electron — that means it becomes a positive ion (because now it has more protons than electrons).
This process is called ionization.

Explanation: When an atom loses an electron, it becomes positively charged. This can happen when atoms interact or gain/lose energy.

3. This diagram shows _________.

The diagram shows a conductor (like a wire) with many negative charges (electrons) moving from left to right. There’s an arrow showing electrons entering from the left and exiting as positive charges on the right — which actually represents the *direction of conventional current* (opposite to electron flow).

But since the question says “label and explain what is happening in the conductor above,” we focus on the movement of electrons.

Label: Electrons flowing through a conductor.

Explanation: In a conductor, electrons move freely. When voltage is applied, they drift in one direction — this movement is electric current. Even though electrons are negative, we traditionally say current flows from positive to negative (conventional current), opposite to electron flow.

4. All matter is made of _______________.

→ atoms

All things around us — solids, liquids, gases — are made of tiny building blocks called atoms.

---

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

→ electric (or sometimes “charge” alone, but “electric” fits best here)

Actually, looking at context, it might be expecting “negative, positive, or neutral” — but the sentence says “an ___ charge”, so likely “electric”.

Wait — let’s read again: “Small particles in an atom have an ________ charge.”

Better answer: specific or type of — but that’s vague.

Actually, standard answer: electric charge.

But perhaps they want: positive, negative, or neutral — but the blank is singular.

Looking at next questions, probably they mean: electric

Alternatively, maybe “inherent” — no.

Best fit: electric

But let’s check common phrasing: “Particles in an atom carry electric charge.”

Yes → electric

6. Electrons have a _______________ charge.

→ negative

Always remember: electrons are negative.

---

7. Protons have a _______________ charge.

→ positive

Protons are positive.

---

8. Inner orbiting electrons are called _______________.

→ core electrons

These are electrons close to the nucleus, not involved in bonding.

---

9. Outer orbiting electrons are called _______________.

→ valence electrons

These are the ones involved in chemical reactions and electricity conduction.

---

10. We use wires to produce an orderly _______________.

→ flow of electrons (or electric current)

Wires provide a path for electrons to move in a controlled way — that’s electric current.

Most accurate: flow of electrons or current

But “orderly” suggests “current”

→ electric current

Now, let’s compile all answers clearly.

---

Final Answer:

1. Protons (+), Neutrons (0), Electrons (-) — label accordingly on diagrams.

2. The top atom is neutral; the bottom atom is losing an electron and becoming a positive ion. This is ionization.

3. This diagram shows electrons flowing through a conductor. Explanation: Electrons move through the material, creating electric current. The arrows show direction of electron flow (left to right), while conventional current is opposite.

5. electric
6. negative
7. positive
8. core electrons
9. valence electrons
10. electric current

(Note: For #5, if “electric” feels too vague, some curricula accept “charge” — but “electric” is more precise. If unsure, “charge” is safer.)

Actually, rethinking #5: “Small particles in an atom have an ________ charge.” — the word “an” suggests a vowel sound. So “electric” works. But perhaps they expect “type of” — no.

Standard textbook phrasing: “Particles in an atom have electric charge.”

So I’ll stick with electric.
