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 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, it was Antoine Laurent de Lavoisier who isolated nitrogen. He emphasized that this gas does not combine with any other chemical element. Carl Wilhelm Scheele and Joseph Priestley also studied this gas. The last was the chemist Jean-Antoine Chaptal in 1832 to whom the Latin term nitrogen from the Greek nitro was suggested. It was named N later in the 19th century. Plants produce nitrogen composite proteins that are easily dissolved in the soil. Some of the nitrogen dissolved in the soil comes from the atmosphere to form nitric acid, nitrogen reacts with oxygen in lightning, composing many compounds called nitrogen oxides, which in turn react with water composed of nitric acid, which has carried the rain to the ground. In this case, nitrogen gas is an important element for organisms. It represents approximately 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 chemical element, tasteless and odorless. Difficult to soluble in water and cannot react easily with many other elements. On a daily basis, most organisms consume nitrogen present in their diet. It makes up about 80% of the atmosphere, but oxygen gas only covers 20% of the atmosphere. It can be condensed into liquid nitrogen. The boiling point of nitrogen is at a temperature of 195.8 m and freezes at -9. 209 m....... middle of paper ...... the production of nitric acid and other chemicals. As has been noted, nitrogen is a chemical element with atomic number seven and it makes up approximately 78% of the Earth's atmosphere. In 1786, it was Antoine Laurent de Lavoisier who isolated nitrogen. Of course, nitrogen fertilizers are useful in the agricultural industry. It acts effectively on the environment such as soil, groundwater and organisms. Therefore, it will destroy very soon if used so much. Additionally, legumes, such as peas and soybeans, produce protein nitrogen found in the air using a specific type of bacteria. One of the important applications is to use a liquid to store a biological substance. In reality, nitrogen gas is a necessary element for organisms. Furthermore, this represents approximately 4/5 of the Earth's atmosphere. In my opinion, farmers and businesses need to reduce the use of nitrogen fertilizers and replace them with natural fertilizers..
