As the name suggests, the coordination compounds are compounds involving coordination bonds in their formation.

Central metal atom of a coordination compound can possess two kinds of valencies i.e. primary valency and secondary valency, and these valencies determine the structure of a coordination compound.

Chemistry is the subject of different elements of the Mendeleev’s periodic table, reactions and mechanisms, physical and chemical properties and finally the application of these elements. There are 118 elements reported in nature and only one element, which is carbon [Atomic no 6, symbol C] is founder of organic chemistry discipline.

How do we understand the classification of Colloids ?

In surface chemistry, the word colloid refers to a colloidal solution which is an intermediary between true solution and suspension.

In absorption, a substance enters another substance and gets distributed uniformly throughout the 2nd substance.

A compound comprises two or more than elements, and the chemistry formula reveals the number of atoms present in each component. The chemical formula contains symbols of the element’s atoms in the compound. It also reflects the number of atoms present in each element.

Dmitri Mendeleev was one of the great chemists of the 19th century. He correctly predicted the properties of more than three undiscovered elements. His contributions to chemistry won him the title of the father of the modern periodic table.

Robert Boyle was a chemist of the 17th century and a founder of the modern chemistry.

The law of conservation of matter is a fundamental law in science. It is also known as the law of conservation of mass. The later is used in physics while the former in chemistry. It is one of the laws of chemical combinations in chemistry. The law has huge applications in chemistry, physics, and engineering. In a closed system, the exchange of matter is restricted across its boundaries. So, there is no matter entering the system or leaving the system. Thus, the flow of matter in and out of the system is zero. These statements are true only for a closed system with no nuclear change. We can apply the law to systems which are subjected to physical and chemical changes, not nuclear changes. This will be better understood as we go through the article.
