There are several chemical formulae, however, here is a list of most important Chemical Formulas in chemistry. Sl.No Name of the Chemical Compound Formula 1 Acetic acid formula CH3COOH 2 Aluminium hydroxide formula Al(OH)3 3 Acetate formula CH3COO- 4 Acetone…
In order to write a chemical formula, it is important to know the symbol of the elements present in the compound, formula of the radicals and the valency of the elements in that compound. Following points should be kept in…
While the term ‘chemical formula’ typically refers to the molecular formula of a compound (which denotes the total number of atoms of each constituent element in one molecule of the compound), the compositions of chemical compounds can be expressed in…
There are molecules and ions for which drawing a single Lewis structure is not possible. For example, we can write two structures of O3. In (A), the oxygen-oxygen bond on the left is a double bond, and the oxygen-oxygen bond on…
Bond Length During chemical bonding, when the atoms come closer to each other, the attraction takes place between them, and the potential energy of the system keeps on decreasing till a particular distance at which the potential energy is minimum.…
The following steps are adopted for writing the Lewis dot structures or Lewis structures: Step 1: Calculate the number of electrons required for drawing the structure by adding the valence electrons of the combining atoms. For example, in methane, a CH4 molecule, there are…
The bond formed as a result of strong electrostatic forces of attraction between a positively and negatively charged species is called an electrovalent or ionic bond. The positively and negatively charged ions are aggregated in an ordered arrangement called the crystal…
Albrecht Kössel and Gilbert Lewis were the first to explain the formation of chemical bonds successfully in the year 1916. They explained chemical bonding on the basis of the inertness of noble gases. Lewis Theory of Chemical Bonding Lewis symbols for…
Chemical bonding refers to the formation of a chemical bond between two or more atoms, molecules or ions to give rise to a chemical compound. These chemical bonds are what keep the atoms together in the resulting compound.
