Elements are the simplest and simplest forms of matter. The contents of the elements consist of uniform atoms and cannot be separated into simpler building blocks by chemical methods. All other substances are compounds, alloys or mixtures. For example, it has a molecular structure formed by the elements Water, Hydrogen and Oxygen.
The outer layer of the Earth is called Stone Globe. The substances in the earth’s crust also consist of elements, compounds, alloys and mixtures.
Have you ever thought about the most common elements when we consider substances in the earth’s crust? Although there are many studies on this subject, the most valid ones are the studies of David Darling and Israel Science & Technology Center. Both studies give close results.
Top 10 Most Common Elements in the Earth Crust
Oxygen (O) (46.6%)
It is the most abundant element in the earth’s crust. It constitutes almost half of the earth’s crust by mass. It also makes up 21% of the atmosphere. Since oxygen is a highly reactive element under Earth conditions, it usually exists in compound form. For example, iron rust forms when iron and oxygen react. Combustion reactions also occur as a result of the reaction of substances with oxygen. Oxygen is the most abundant element in the human body in terms of mass. All living things that breathe with oxygen constantly need them.
Silicon (Si) (27.7%)
Silicon, the second most common element, contains more than 1/4 of the mass of the earth’s crust. creates. The most common first and second elements 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 highly valuable ingredient 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 pure form in the earth’s crust. Aluminum oxide is the most common aluminum compound. Aluminum 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 common metal in free form in nature. This element, which people have processed and used for thousands of years, is important enough to open and close an era in the development of humanity. As a matter of fact, it appears at many points in daily life. Iron element, which has an important function in our body, is indispensable for humans. Its most important function in the human body is blood production.
Calcium (Ca) (3.6%)
The fifth most common element, Calcium is also a highly reactive element and is found in pure form in nature. it is impossible. It can react with water and oxygen without any triggering. Calcium and its compounds are used in a wide variety of places in the production sector. The most common products we come across with calcium 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, again a highly reactive element. As with other reactive elements, it is almost impossible to find it in pure form in nature. When thrown into water, it reacts so quickly that explosions are seen during this reaction. The most common products in daily life are table salt and soda. It is a very important element for our body. Its most important function in the human body is to participate in the structure of the blood and to play 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 that we will encounter with potassium in daily life are soap, fertilizers and detergents. It is another very important element 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 cell structure.
Magnesium (Mg) (2.09)
Magnesium, the eighth most common element, is also highly reactive and almost impossible to be found in pure form in nature. Today, it is most commonly used in aviation industry, pharmacy and photography. Its most important function in the human body is that it is used in bone and muscle construction and plays an active role in the nervous system.
Titanium (Ti) (0.44%)
The ninth most common element, Titanium, can be found in free form and alloyed in nature. As strong and durable as steel but 45% lighter than steel. Since it has a unique resistance against sea water, its alloys are used especially in metal hull ships. It is also very resistant to temperature changes and high temperatures. So 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. It is the cleanest fuel because only water is produced when it burns, and it is generally used in fuel technologies today. It would be funny to talk about the importance of organic compounds for our body as they are the basic building blocks. It is the third most abundant element in the human body by mass.
