Elements are the simplest forms of matter. The contents of the elements consist of uniform atoms and cannot be separated into simpler basic units of matter by chemical methods. All other substances are compounds, alloys, or mixtures. For example, water has a molecular structure composed of Hydrogen and Oxygen elements.
The outer layer of the Earth is called Earth Crust (Stone Sphere). Substances in the earth’s crust also consist of elements, compounds, alloys, and mixtures.
Have you ever thought about the elements we will come across most when we consider the ingredients in the earth’s crust? Although there are many studies on this subject, the most accepted ones are the studies of David Darling and the Israel Science & Technology Center. Both studies give close results.
Top 10 Most Abundant Elements on Earth’s Crust
- Oxygen (O) (46.6%)
It is the most abundant element in the earth’s crust. It makes up almost half of the earth’s crust in mass. It also makes up 21% of the atmosphere. Since oxygen is a highly reactive element in world conditions, it is usually found as a compound. For example, when iron and oxygen react, iron rust forms. Combustion reactions also occur as a result of the reaction of substances with oxygen. Oxygen is the most abundant element in the human body. All living creatures with oxygen constantly need oxygen.
- Silicon (Si) (27.7%)
The second most common element, silicon, makes up more than 1/4 of the mass of the earth’s crust. The first and second elements most commonly found in the earth’s crust also form Silicon Dioxide, the most common compound in the earth’s crust. Although most people know Silicon Dioxide as sand, this compound can also be found in the form of quartz and rock crystals. Silicon is also a very valuable component in the electronics manufacturing industry.
- Aluminum (Al) (8.13%)
Aluminum, the third most common element, is also the most common metal in the earth’s crust. However, it is almost impossible to find Aluminum in the earth’s crust in its pure form. Aluminum oxide is the most common Aluminum compound. Aluminum profiles and Aluminum alloys are widely used especially in kitchenware and aviation.
- Iron (Fe) (5.0%)
Iron, the fourth most common element, is also the most commonly found metal in nature. This element, which people have been processing and using for thousands of years, is important enough to open and close the era in the development of humanity. We come across many points in daily life. Iron element, which has an important function in our body, is a must for people. The most important function in the human body is blood production.
- Calcium (Ca) (3.6%)
Calcium, which is the fifth most common element, is also a highly reactive element and it is impossible to find it in its pure form in nature. It can react with water and oxygen without any triggering. Calcium and its compounds are used in various places in the production sector. The most common products we encounter in daily life are toothpaste, lime, and chalk. It is a very important element for our body. Its most important function in the human body is its use in bone formation.
- Sodium (Na) (2.8%)
The sixth most common element is Sodium, which is also a highly reactive element. As with other reactive elements, it is almost impossible to find them pure. When it is thrown into the water, it reacts so quickly that explosions are seen during this reaction. The most common products we encounter in daily life are salt and soda. It is a very important element for our body. Its most important function in the human body is that it participates in the structure of the blood and plays an important role in the nervous system.
- Potassium (K) (2.59%)
Potassium, the seventh most common element, is also highly reactive and very difficult to find in pure form in nature. The most common products we will encounter with potassium in daily life are soap, fertilizers, and detergents. It is another element that is very important for our body. Its most important function in the human body is to play an important role in the nervous system and to be used in the cell structure.v
- Magnesium (Mg) (2.09)
Magnesium, the eighth most common element, is also highly reactive and almost impossible to be found in its pure form in nature. Today, it is most commonly used in the aviation industry, pharmacy, and photography. Its most important function in the human body is its use in bone and muscle building and it plays an active role in the nervous system.
- Titanium (Ti) (0.44%)
Titanium, the ninth most common element, can be found in nature in free form and alloy. It is as strong and durable as steel, but 45% lighter than steel. Since it has a unique resistance to seawater, its alloys are used especially in ships with metal bodies. It is also highly resistant to temperature changes and high temperatures. Therefore, it is widely needed in the space industry.
- Hydrogen (H) (0.14%)
Hydrogen, the lightest element, is the 10th most common element in the earth’s crust. It makes up almost 75% of the mass of the universe, meaning it is the most common element in the universe. When it burns, it is the cleanest fuel since only water emerges, and today it is generally used in fuel technologies. It will be funny to talk about the importance of organic compounds for our bodies as it is the basic cell structure. It is the third most abundant element in the human body.
