Chemistry is the study of the structures, physical properties, and chemical properties of material substances. It is very important to understand that all gases, liquids and solids are not the same. All are different in terms of their composition. This is the reason why the classification of the matter is very important.
When two or more elements chemically combine in a fixed ratio by mass, the obtained product is known as a compound.Compounds can be defined as substances consisting of 2 or more different types of elements in a fixed ratio of their atoms. When the elements combine, some individual property of the elements is lost and the newly formed compound has n...
We can define elements as a species of atoms that have the same number of protons in their atomic nuclei.Although an element’s atoms have the same number of protons, they can have different numbers of neutrons and hence different masses. Isotopes:When atoms of the same element have different numbers of neutrons, they are known as isotopes. As of no...

Compounds made from non-metal elements that are bonded together usually form molecules. Compounds including both a metal element and a non-metal element bonded together do not form...
Chemistry is the study of the transformation of matter from one form to the other. These transformations often occur as a result of the combination of two different types of matter. The combination of different elements to form compounds is governed by certain basic rules.

Sep 21, 2022 · A combination reaction is a reaction in which two or more substances combine to form a single new substance. Combination reactions can also be called synthesis reactions. The general form of a combination reaction is: A + B → AB A + B → AB. One combination reaction is two elements combining to form a compound.
