What does the Lewis theory explain?
Answers
Answer:
Lewis theory refers to an immensely influential theory of categorizing acids and bases. It was proposed in 1923 by Gilbert Lewis. Any chemical compound that attaches itself to a pair of electrons in another molecule is regarded as acid while the molecule that donates its electron pairs is regarded as a base. Acids and bases react and neutralize each other. This reaction is called neutralization. After neutralization, a new compound is created in which the chemical bond (that is formed from the electron pair) comes from a single reactant. As per the Lewis acid base theory, metal ions, nonmetallic (sulfur, nitrogen, phosphorous) oxides, hydrogen ion donors, proton donors, and compounds such as silica, alumina, and aluminum chloride are characterized as acids.
Kossel Lewis Theory Explanation:
The scientists Kossel and Lewis developed the theory of chemical bonds or the theory of electronic valency which is popularly known as Kossel Lewis theory. This theory is based on the principle that a higher energy state is the least stable. Therefore, every system aims to achieve stability or equilibrium by losing some energy.
This principle can be used to explain how chemical bonds are formed between any two atoms. In the atomic system, to attain stability, the atom has to attain an octet configuration in its outermost shell. This is achieved by gaining, losing, or sharing electrons.
