Chemical Compound
1: Who was the first woman President of India?
A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. There will be a fixed ratio for a chemical compound determining the composition of it. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The ratio of each element is usually expressed by a chemical formula. In the simplest way, you can define a chemical compound as “a substance that is made up of two or more elements”. Water, carbon dioxide and table salt are three examples for chemical compounds.
Common Names of Chemical Compounds
For every chemical compound, there will be a chemical name or scientific name and a common name or popular name. Scientists or chemists identify a particular chemical compound from its scientific name. But in general, they are known by their common name and many of them are a part of our day to day life. For instance, the chemical name of NaCl is Sodium chloride and its common name is salt.

Chemical Formula
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers and sometimes also other symbols such as parentheses, dashes, brackets, commas and plus and minus signs. In other words, a chemical formula represents the ratio of atoms per element that make up the chemical compound. This is done through the use of subscripts. The subscript that lies to the right of the symbol for each element indicates the number of atoms of that element that make up that chemical compound.
A chemical formula reflects a lot of information about the chemical substance it represents such as how many and what atoms they are made of as well as the way the atoms are arranged
Now let us have a look at the common names and formulas of some important chemical compounds.
