Interactive Foldable Periodic Table - Teaching & Learning Toolbox ... - Free Printable

Since none of the user options (ExplainAnswer, TeachTopic, GeneratePractice) are set to true, I will skip those sections and go straight to solving the problem based on the image provided.

Looking at the periodic table in the image, we can see that each element box contains:

- Atomic number (top left or bottom, depending on layout — here it’s usually top left)
- Element symbol (center)
- Element name (below symbol)
- Relative atomic mass (top right or above symbol)

In the key shown in the center-top of the table, it labels:

→ Top number = relative atomic mass
→ Middle = symbol
→ Below symbol = name
→ Bottom number = atomic (proton) number

But looking at actual boxes like Lithium (Li):

It shows:
```
7
Li
lithium
3
```

So according to the key:
- 7 = relative atomic mass
- Li = symbol
- lithium = name
- 3 = atomic (proton) number

This matches standard periodic tables: atomic number is the smaller whole number (number of protons), and atomic mass is the larger decimal (or rounded) number.

Now, let’s verify with another element — say, Carbon (C):

Box says:
```
12
C
carbon
6
```

Atomic number = 6 → correct (Carbon has 6 protons)
Atomic mass ≈ 12 → correct (most common isotope)

Another one: Oxygen (O)
```
16
O
oxygen
8
```

Atomic number = 8 → correct
Atomic mass = 16 → correct for O-16

So the pattern holds.

Therefore, for any element in this table:

→ The atomic number (number of protons) is the bottom number in the box.
→ The relative atomic mass is the top number.

This is consistent across all elements shown.

Final Answer:
The atomic number (proton number) is the bottom number in each element box. The relative atomic mass is the top number.
