SOLUTION: Thanh ho per 1 protons neutrons and electrons practice ... - Free Printable

It looks like you've uploaded a table with atomic information for various elements, but the lower portion of the table is blurred or obscured. However, I can help you solve and explain the problem based on the visible part of the table.

Let’s analyze the visible data and then explain how to complete such a table.

🔍 Visible Data in the Table:

| Atomic Symbol | Atomic Number | Protons | Neutrons | Electrons | Mass Number | Atomic Mass |
|---------------|----------------|---------|----------|-----------|--------------|-------------|
| B | 5 | 5 | 6 | 5 | 11 | 10.811 |
| Na | 11 | 11 | 13 | 11 | 24 | 22.989770 |
| Ga | 31 | 31 | 37 | 31 | 68 | 69.723 |

✔ Key Concepts:

Let’s review the relationships between these atomic properties:

1. Atomic Number (Z) = Number of protons
- This defines the element.
- For neutral atoms: Number of electrons = Number of protons

2. Mass Number (A) = Number of protons + Number of neutrons
- So: Neutrons = Mass Number – Protons

3. Atomic Mass ≈ Weighted average of isotopes (in atomic mass units, u)

4. Electrons = Protons (for neutral atoms)
- If it's an ion, electrons differ, but here all are neutral.

🧮 Let’s Verify Each Row:

#### 1. Boron (B)
- Atomic Number = 5 → Protons = 5
- Electrons = 5 (neutral atom)
- Mass Number = 11
- Neutrons = 11 – 5 = 6 ✔
- Atomic Mass = 10.811 u (correct average)

✔ All values match.

#### 2. Sodium (Na)
- Atomic Number = 11 → Protons = 11
- Electrons = 11 (neutral)
- Neutrons = 13
- Mass Number = 11 + 13 = 24 ✔
- Atomic Mass = 22.989770 u (correct)

✔ Correct.

#### 3. Gallium (Ga)
- Atomic Number = 31 → Protons = 31
- Electrons = 31
- Neutrons = 37
- Mass Number = 31 + 37 = 68 ✔
- Atomic Mass = 69.723 u (correct average)

✔ Correct.

📌 How to Complete the Table (if more rows were visible):

For any element:
1. Use the Atomic Number to find:
- Protons = Atomic Number
- Electrons = Protons (if neutral)
2. Use Mass Number to find:
- Neutrons = Mass Number – Protons
3. Atomic Mass is usually given (from periodic table) and may vary slightly due to isotopes.

> ⚠️ Note: The mass number is the sum of protons and neutrons in a specific isotope. It's often an integer, while atomic mass is a weighted average and may have decimals.

❓ What if You Need to Fill in Missing Values?

Example: Suppose you're given:
- Atomic Symbol: C
- Atomic Number: 6
- Mass Number: 12

Then:
- Protons = 6
- Electrons = 6
- Neutrons = 12 – 6 = 6
- Atomic Mass ≈ 12.011 u (from periodic table)

🚫 Issue with the Image:

The rest of the table below Ga is blurred, so I cannot read or fill in those entries. But if you provide:
- The atomic symbols or names,
- Or the missing values you want filled in,

I can help complete them!

✔ Summary:

You’ve been given a table showing atomic structure data. The visible rows are correctly filled out using standard atomic principles:

- Protons = Atomic Number
- Electrons = Protons (for neutral atoms)
- Neutrons = Mass Number – Protons
- Atomic Mass is from the periodic table (average of isotopes)

If you can clarify what you'd like solved — for example:
- Completing the full table?
- Identifying errors?
- Understanding how to calculate missing values?
