What is Element and Compound

The 118 authorized elements can be broadly categorized as metals and non-metals. Metals gained significance not only due to their large number but also due to their widespread use in various fields of industry. Nevertheless, the role of non-metals is not insignificant in day-to-day life. The importance of oxygen and carbon in the biosphere is incredible. Apart from this, some non-metals in the form of their compounds occupy the most pivotal position in the industrial sector and they are rightly called industrial chemicals

Nitrogen, the element which is well known for its abundance in the atmospheric air, is the most important nutrient for plants. Therefore, the various compounds of nitrogen are manufactured for the use as fertilizers. Sulphur and phosphorous also form a part of the fertilizer industry. In addition to this common use, certain compounds are useful for specific purposes such as phosphorous in the match industry. Similarly common salt, a compound of chlorine, forms an important part of our diel. 

However, there are some compounds, such as, nitric acid, sulphuric acid, hydrochloric acid, etc.,  which form an inevitable part of almost every chemical industry. In fact, the yearly consumption of sulphuric acid in a country is taken as an indication which reflects the status of chemical industy in that country. In this context, it should be recalled that sulphuric acid is popularly known as king of chemicals.

Difference between Element and Compound


Element


1.Element is composed of one type of atoms. 
2.The number of elements is about 112.
3.The property of the element is due to its microscopic particle, atom.
4.Elements do not decompose into simple substances by physical and chemical actions. 

Compound

1.A compound is composed of two or more atoms. 
2.The number of elements is very high.  
3.The properties of compounds are due to their minutest particles, molecules. 
4.Organics can be decomposed into simple substances by physical and chemical actions. Examples - Hydrogen, Nitrogen, Carbon, PhosphorusYougico Example - Water Sodium Chloroid, Copper Sulfate etc.
