Periodic Table Worksheet for students to fill in missing information about elements.

Let’s go step by step to fill in the missing information for each element using what we know about the periodic table.

We need to find:
- Atomic Number (top left)
- Element Symbol (center, big letter(s))
- Element Name (below symbol)
- Atomic Mass (bottom, decimal number)

We’ll use standard periodic table values. Let’s go box by box.

---

Row 1:

1. B → This is Boron.
- Atomic Number: 5
- Element Name: Boron
- Atomic Mass: ~10.81

2. Aluminum → Symbol is Al.
- Atomic Number: 13
- Atomic Mass: ~26.98

3. 56 → That’s the atomic number. Element with atomic number 56 is Barium.
- Symbol: Ba
- Name: Barium
- Atomic Mass: ~137.33

4. Sodium → Symbol is Na.
- Atomic Number: 11
- Atomic Mass: ~22.99

5. Co → Cobalt.
- Atomic Number: 27
- Name: Cobalt
- Atomic Mass: ~58.93

---

Row 2:

6. 63.546 → That’s copper’s atomic mass.
- Symbol: Cu
- Name: Copper
- Atomic Number: 29

7. 53 → Atomic number 53 is Iodine.
- Symbol: I
- Name: Iodine
- Atomic Mass: ~126.90

8. Tin → Symbol is Sn.
- Atomic Number: 50
- Atomic Mass: ~118.71

9. W → Tungsten.
- Atomic Number: 74
- Name: Tungsten
- Atomic Mass: ~183.84

10. 72.631 → That’s Germanium’s atomic mass.
- Symbol: Ge
- Name: Germanium
- Atomic Number: 32

---

Row 3:

11. 93 → Atomic number 93 is Neptunium.
- Symbol: Np
- Name: Neptunium
- Atomic Mass: ~237 (but since it's radioactive and varies, sometimes listed as [237] — but for this worksheet, we can use 237.0 or leave as is if not specified. However, looking at other masses given, they are precise decimals. Actually, standard value used in schools is often 237.0 for simplicity.)

Wait — let me double-check: The problem gives “93” as atomic number, so we need name, symbol, and mass.

Actually, looking again — the box has “93” on top, so that’s atomic number. We need to fill the rest.

But wait — in row 3, first box says “93” — that’s atomic number → Neptunium → Np → mass ≈ 237.0 (we’ll use 237.0 for consistency with others having one decimal).

But actually, let’s check all carefully.

Alternatively, maybe some boxes have mass already? Let’s re-scan:

Looking back at original image description:

In Row 3:

First box: “93” → atomic number → so we need symbol, name, mass.

Second box: “32.066” → that’s sulfur’s atomic mass? Wait no — sulfur is 32.06, but atomic number 16. But here, only mass is given → so we need to find which element has atomic mass ~32.066 → that’s Sulfur (S), atomic number 16.

Third box: “Kr” → Krypton → atomic number 36, mass ~83.80

Fourth box: “88.906” → that’s Yttrium? No — Yttrium is 88.91, atomic number 39. Yes.

Fifth box: “Gold” → Au, atomic number 79, mass ~196.97

Wait — let’s list them properly.

Actually, let’s make a grid based on positions.

There are 4 rows × 5 columns = 20 boxes.

Let me label them by position (row, col):

Row 1:
(1,1): B → Boron → Z=5, mass=10.81
(1,2): Aluminum → Al, Z=13, mass=26.98
(1,3): 56 → Barium, Ba, mass=137.33
(1,4): Sodium → Na, Z=11, mass=22.99
(1,5): Co → Cobalt, Z=27, mass=58.93

Row 2:
(2,1): 63.546 → Copper, Cu, Z=29
(2,2): 53 → Iodine, I, mass=126.90
(2,3): Tin → Sn, Z=50, mass=118.71
(2,4): W → Tungsten, Z=74, mass=183.84
(2,5): 72.631 → Germanium, Ge, Z=32

Row 3:
(3,1): 93 → Neptunium, Np, mass=237.0 (approx)
(3,2): 32.066 → Sulfur, S, Z=16
(3,3): Kr → Krypton, Z=36, mass=83.80
(3,4): 88.906 → Yttrium, Y, Z=39
(3,5): Gold → Au, Z=79, mass=196.97

Row 4:
(4,1): Europium → Eu, Z=63, mass=151.96
(4,2): Fe → Iron, Z=26, mass=55.85
(4,3): 82 → Lead, Pb, mass=207.2
(4,4): Potassium → K, Z=19, mass=39.10
(4,5): 107.868 → Silver, Ag, Z=47

Now let’s verify each with standard values:

Confirming key ones:

- Boron: Z=5, mass=10.81 ✔️
- Aluminum: Z=13, mass=26.98 ✔️
- Barium: Z=56, mass=137.33 ✔️
- Sodium: Z=11, mass=22.99 ✔️
- Cobalt: Z=27, mass=58.93 ✔️

Copper: mass=63.546 → Z=29 ✔️
Iodine: Z=53, mass=126.90 ✔️
Tin: Z=50, mass=118.71 ✔️
Tungsten: Z=74, mass=183.84 ✔️
Germanium: mass=72.631 → Z=32 ✔️

Neptunium: Z=93, mass≈237.0 (commonly used value) ✔️
Sulfur: mass=32.066 → Z=16 ✔️
Krypton: Z=36, mass=83.80 ✔️
Yttrium: mass=88.906 → Z=39 ✔️
Gold: Z=79, mass=196.97 ✔️

Europium: Z=63, mass=151.96 ✔️
Iron: Z=26, mass=55.85 ✔️
Lead: Z=82, mass=207.2 ✔️
Potassium: Z=19, mass=39.10 ✔️
Silver: mass=107.868 → Z=47 ✔️

All match standard periodic table values.

Now, to present the answer clearly, we’ll list each box’s completed info in order.

Since the worksheet expects you to fill each box with the missing parts, we’ll write for each box what should be filled.

But since the user just wants the final answer, and the task is to complete the missing info, we can list the full set of answers per box.

However, the instruction says: "Final Answer: [Provide only the final correct answer]"

So perhaps we should output the completed grid as text.

But to keep it simple, let’s list each box’s content in row-major order, showing what was missing and now filled.

Actually, since the original had some fields given, we need to output the full info for each box as it should appear.

But to avoid confusion, I’ll write the answer as a list of 20 entries, each being the four pieces: Atomic Number, Symbol, Name, Atomic Mass — in that order, as shown in the example (H box).

Example from top: For Hydrogen, it showed:
Atomic Number: 1
Symbol: H
Name: Hydrogen
Mass: 1.008

So for each box, we’ll give those four values.

Let’s do it:

Box 1 (B):
Atomic Number: 5
Symbol: B
Name: Boron
Atomic Mass: 10.81

Box 2 (Aluminum):
Atomic Number: 13
Symbol: Al
Name: Aluminum
Atomic Mass: 26.98

Box 3 (56):
Atomic Number: 56
Symbol: Ba
Name: Barium
Atomic Mass: 137.33

Box 4 (Sodium):
Atomic Number: 11
Symbol: Na
Name: Sodium
Atomic Mass: 22.99

Box 5 (Co):
Atomic Number: 27
Symbol: Co
Name: Cobalt
Atomic Mass: 58.93

Box 6 (63.546):
Atomic Number: 29
Symbol: Cu
Name: Copper
Atomic Mass: 63.546

Box 7 (53):
Atomic Number: 53
Symbol: I
Name: Iodine
Atomic Mass: 126.90

Box 8 (Tin):
Atomic Number: 50
Symbol: Sn
Name: Tin
Atomic Mass: 118.71

Box 9 (W):
Atomic Number: 74
Symbol: W
Name: Tungsten
Atomic Mass: 183.84

Box 10 (72.631):
Atomic Number: 32
Symbol: Ge
Name: Germanium
Atomic Mass: 72.631

Box 11 (93):
Atomic Number: 93
Symbol: Np
Name: Neptunium
Atomic Mass: 237.0

Box 12 (32.066):
Atomic Number: 16
Symbol: S
Name: Sulfur
Atomic Mass: 32.066

Box 13 (Kr):
Atomic Number: 36
Symbol: Kr
Name: Krypton
Atomic Mass: 83.80

Box 14 (88.906):
Atomic Number: 39
Symbol: Y
Name: Yttrium
Atomic Mass: 88.906

Box 15 (Gold):
Atomic Number: 79
Symbol: Au
Name: Gold
Atomic Mass: 196.97

Box 16 (Europium):
Atomic Number: 63
Symbol: Eu
Name: Europium
Atomic Mass: 151.96

Box 17 (Fe):
Atomic Number: 26
Symbol: Fe
Name: Iron
Atomic Mass: 55.85

Box 18 (82):
Atomic Number: 82
Symbol: Pb
Name: Lead
Atomic Mass: 207.2

Box 19 (Potassium):
Atomic Number: 19
Symbol: K
Name: Potassium
Atomic Mass: 39.10

Box 20 (107.868):
Atomic Number: 47
Symbol: Ag
Name: Silver
Atomic Mass: 107.868

I think that’s all. Now, to present the final answer neatly.

Since the worksheet likely expects you to write the missing parts in each box, but for our purpose, listing the full data per box is fine.

But to match the format, perhaps we can say:

For each element, here is the complete information:

[Then list]

But the instruction says "Final Answer" only after reasoning, and no extra text.

So I'll compile the answers in a clean way.

Actually, since the user might expect the filled worksheet, but we can't draw, so text list is best.

I’ll write the final answer as a numbered list corresponding to the boxes left to right, top to bottom.
