Periodic Table Worksheet for learning element information.

Let's solve this Periodic Table Worksheet step by step. The goal is to fill in the missing information for each element based on the periodic table. Each box contains one piece of information (atomic number, symbol, name, or atomic mass), and we need to use our knowledge of the periodic table to complete the rest.

---

🔍 Key Information:

For each element, we need to know:
- Atomic Number – number of protons
- Element Symbol – chemical symbol (e.g., H for Hydrogen)
- Element Name – full name of the element
- Atomic Mass – average mass of atoms (in atomic mass units)

We'll go through each box row by row.
