Visual representation of common chemical elements with their names and symbols.

This image presents a matching exercise. The goal is to correctly pair the chemical symbols (in circles) with their corresponding element names (in rectangles).

I will solve this by identifying each symbol and matching it to its correct name based on standard chemical nomenclature.

Step 1: List all the chemical symbols shown in the image.

Looking at the circles, I can identify the following symbols:
- He
- Ca
- O
- N
- Na
- F
- C
- Fe
- Mg
- K
- H
- Ar
- Cl

Step 2: List all the element names provided in the rectangles.

The names are:
- Hydrogen
- Chlorine
- Argon
- Potassium
- Iron
- Calcium
- Oxygen
- Fluorine
- Sodium
- Magnesium
- Helium
- Carbon
- Nitrogen

Step 3: Match each symbol to its correct name.

Based on the periodic table:
- He = Helium
- Ca = Calcium
- O = Oxygen
- N = Nitrogen
- Na = Sodium
- F = Fluorine
- C = Carbon
- Fe = Iron
- Mg = Magnesium
- K = Potassium
- H = Hydrogen
- Ar = Argon
- Cl = Chlorine

Solution:

Here is the complete list of correct matches:

- He → Helium
- Ca → Calcium
- O → Oxygen
- N → Nitrogen
- Na → Sodium
- F → Fluorine
- C → Carbon
- Fe → Iron
- Mg → Magnesium
- K → Potassium
- H → Hydrogen
- Ar → Argon
- Cl → Chlorine

This completes the matching task. All symbols have been correctly paired with their corresponding element names.
