In life we ​​have heard a lot about nitrogen gas. It is a chemical element with atomic number seven and makes up about 78% of the Earth's atmosphere. It included approximately 4,000 trillion tons of gas. In 1772, nitrogen was discovered by Dr. Daniel Rutherford. He called this gas "fixed air". He began his research on carbon dioxide. In 1786, Antoine Laurent de Lavoisier isolated nitrogen. He emphasized that this gas did not combine with any other chemical element. Furthermore, Carl Wilhelm Scheele and Joseph Priestley studied this gas. The last was the chemist Jean-Antoine Chaptal in 1832 to whom the Latin term nitrogen was suggested from the Greek nitro. It was called N later in the 19th century. Plants produce nitrogenous composite proteins that are easily dissolved in the soil. Some of the nitrogen dissolved in the ground comes from the atmosphere to form nitric acid, reacts with oxygen in the event of lightning a component of numerous compounds known as nitrogen oxides, which in turn react with water consisting of nitric acid, which suffered rain to the ground. In that case, nitrogen is one of the important elements for organisms. It makes up about 4/5 of the Earth's atmosphere. What is nitrogen? It has an atomic number seven. It has five electrons in its outer shell. It is a non-metallic, tasteless and odorless chemical element. Hardly soluble in water and cannot react easily with many other elements. Every day, most organisms consume nitrogen in their food. It makes up about 80% of the atmosphere, but oxygen only covers 20%. It can be condensed in liquid nitrogen. The boiling point of nitrogen is at a temperature of 195.8 m and freezes at -9. 209 m...... middle of paper...... production of nitric acid and other chemicals. As has been noted, nitrogen is a chemical element with atomic number seven and makes up approximately 78% of Earth's atmosphere. In 1786, Antoine Laurent de Lavoisier isolated nitrogen. Of course, nitrogen fertilizer is useful in the agricultural industry. It is effective on the environment such as soil, groundwater and organisms. This way, it will get destroyed very soon if you use it that much. Additionally, legumes, such as peas and soybeans, produce airborne protein nitrogen with the help of a specific type of bacteria. One of the most important applications is the use of liquids to store biological substances. In reality, nitrogen is a necessary element for organisms. Furthermore, it makes up approximately 4/5 of the Earth's atmosphere. In my opinion, farmers and companies must reduce the use of nitrogen fertilizers and replace them with natural fertilizers.
