The Importance of Chemical Elements in Everyday Life

What are chemical elements? Simply put, they are the “building blocks” of the universe. Each element represents a type of atom, the smallest unit of matter. They have names, symbols (one or two letters, such as H for hydrogen or O for oxygen), and atomic numbers that indicate the number of protons in their nuclei. Beyond this seemingly technical definition lies something extraordinary: chemical elements are essential for life and the functioning of everything around us.

From rocks to living beings, metals to everyday objects, everything is composed of chemical elements that combine to form molecules and compounds. For instance:

• Water (H₂O): made up of hydrogen (H) and oxygen (O).
• Table salt (NaCl): consists of sodium (Na) and chlorine (Cl).
• The air we breathe: contains elements like nitrogen (N₂) and oxygen (O₂).

And let’s not forget ourselves: our bodies are also constructed from chemical elements! The six most common are:

1. Carbon (C): the backbone of organic molecules like DNA, proteins, and carbohydrates.
2. Oxygen (O): essential for respiration and energy production.
3. Hydrogen (H): found in water and biological molecules.
4. Nitrogen (N): vital for DNA and proteins.
5. Calcium (Ca): crucial for bones and teeth.
6. Iron (Fe): necessary for oxygen transport in the blood.

The role of chemical elements extends beyond biology; many are key components of the technology we use daily:

• Silicon (Si): the heart of microchips in computers and smartphones.
• Copper (Cu): an excellent conductor in electrical wiring.
• Aluminum (Al): lightweight and strong, ideal for vehicles and construction.
• Lithium (Li): found in rechargeable batteries.
• Uranium (U): used as fuel in nuclear power plants.

Currently, there are 118 known chemical elements. Out of these, 94 occur naturally (like oxygen, carbon, and gold), while 24 have been synthesized in laboratories (such as californium and livermorium). To help us better understand these natural wonders, the Russian chemist Dmitrij Ivanovič Mendeleev created the periodic table in 1869. This tool organizes elements by atomic number and groups them by similar properties.

Keith Enevoldsen's Periodic Table: Everyday Chemistry Examples

When we think back to the periodic table studied in school, it may not always seem approachable! However, thanks to engineer Keith Enevoldsen, this “map” has been updated to illustrate how chemical elements interact with our daily lives. This new perspective makes chemistry feel less abstract and more tangible.

Keith Enevoldsen, a retired engineer passionate about science communication, created a truly unique periodic table: an interactive and illustrated version that shows how chemical elements are used in everyday life. This “illustrated periodic table” aims to make chemistry more accessible and understandable, linking each element to familiar objects or processes.

The strength of this table lies in its simplicity and clarity. Each element is accompanied by an illustration and a brief description explaining its practical use, transforming often abstract symbols and numbers into concrete, relatable examples. It is designed not only for science enthusiasts but also, and especially, for those without advanced scientific training. With clear language and a focus on practical applications, this table captures the attention of everyone.

For example:

• Fluorine: found in your toothpaste, essential for maintaining healthy teeth.
• Boron: present in sports equipment like tennis rackets, thanks to its lightness and strength.
• Sulfur: a key component of proteins in eggs.
• Europium: used in color television screens;
• Cerium: hidden in lighters.
• Cadmium: once popular in paint pigments.

Every element thus becomes more familiar, transitioning from a mere symbol on the periodic table to a concrete part of our daily lives. This illustrated version not only teaches chemistry but also helps us appreciate its practical value and impact on everything around us.

Common Chemical Elements: Discover Their Uses in Daily Life

As we have seen, many of the most common chemical elements are present around us every day, embedded in objects, materials, and processes we often take for granted. But what are they, and how do we use them daily?

Oxygen, for example, is vital for cellular respiration, found in the air we breathe and the water we drink. It is also used in medical settings for respiratory therapies and industrial processes involving combustion. Carbon, on the other hand, is the foundation of all organic molecules and is present in every form of life. Additionally, it is a key component of fossil fuels like coal, oil, and natural gas, which power many of our daily activities.

Another fundamental element is hydrogen, the most abundant element in the universe, which constitutes water and many organic compounds. Beyond its natural role, hydrogen is considered a key resource for sustainable energy due to its use as a clean fuel.

Nitrogen, which makes up most of the Earth's atmosphere, is essential for proteins and nucleic acids in our bodies. It is used to produce fertilizers vital for agriculture and as a refrigerant in the food industry.

But that’s not all: did you know that liquid nitrogen is increasingly used in pest control to combat insect infestations? Its effectiveness lies in its ability to eliminate pests without leaving chemical residues, thus respecting the environment and ensuring high safety standards. A particularly effective example is bed bug extermination with liquid nitrogen, regarded as one of the most advanced solutions for ridding ourselves of these pesky blood-feeding insects. Bed bugs, known for nesting in mattress crevices, are a common problem in accommodations like hotels and B&Bs. With liquid nitrogen, this issue can be addressed quickly, safely, and sustainably. The substance is also effective against other pests, such as mites, fleas, or woodworms.

Calcium also plays a crucial role in our lives, essential for bone and dental health. We regularly obtain it through foods like milk and dairy products, but it is also used in the production of cement and gypsum, indispensable materials for construction. Iron, on the other hand, is vital for oxygen transport in the blood due to hemoglobin and is widely utilized in constructing structures and vehicles, thanks to its strength and versatility.

Sodium, found in common table salt, is another element we encounter daily. It is essential for nerve impulse transmission and fluid balance in our bodies, with sodium chloride being crucial for food preparation and preservation. Silicon, meanwhile, is the backbone of the technology industry. It is used in semiconductor production, found in computers and smartphones, and also contributes to the manufacturing of glass and construction materials like cement.

Among the most versatile metals is aluminum, lightweight and resistant to corrosion, found in cans, kitchen utensils, and even aerospace components. Chlorine is commonly used for disinfecting drinking water and swimming pools, and it is a fundamental ingredient in producing plastics like PVC.

In addition to these elements, there are lesser-known yet equally important ones, such as lithium, which powers rechargeable batteries for electronic devices, or europium, which adds color to television screens.
