Periodic Table of the Elements with a reference table for atomic data.

Problem Description:

The task involves filling in a table with information about various elements using the periodic table provided. The table requires the following details for each element:
1. Element Name
2. Symbol (Letters)
3. Atomic Number (Top Number)
4. Atomic Mass (Bottom Number)
5. Number of Protons (Equals Atomic Number)
6. Number of Electrons (Equals Atomic Number)

Solution Approach:

To solve this problem, we will use the periodic table to find the required information for each element listed in the table. Here’s how we can proceed:

#### Step 1: Understand the Table Structure
- Element Name: The name of the element.
- Symbol: The one or two-letter abbreviation for the element.
- Atomic Number: The number of protons in the nucleus of an atom of the element (also equals the number of electrons in a neutral atom).
- Atomic Mass: The average mass of an atom of the element, usually given in atomic mass units (amu).
- Number of Protons: Equal to the atomic number.
- Number of Electrons: Equal to the atomic number in a neutral atom.

#### Step 2: Fill in the Table
We will go through each row of the table and fill in the missing information using the periodic table.
