Electronegativity Electronegativity (E.N) is the general tendency of an atom in a molecule to draw the shared pair of electrons toward itself. It is defined as an atom’s ability to attract electrons to itself in a chemical bond. It is … Read more
A substance is a type of matter that has specific features and compositions. Substances are made up of atoms and molecules. Each substance has a specific weight and volume. It cannot be separated into distinct types of matter through physical … Read more
A colloid is a heterogenous mixture in which particle size ranges between 1 and 100 nm. The colloidal state consists of two phases: a dispersed phase and a dispersion phase. Dispersed phase: The substance is distributed as colloidal particles. Dispersed … Read more
Nuclear reaction Nuclear reactions are the process in which two atomic nuclei or one atomic nucleus and a subatomic particle (such as a proton or neutron or high energy electron) collide to form one or more nuclides different from parent … Read more
There are two different kinds of electrochemical cells: galvanic cells, which have spontaneous redox reactions that permit continuous electron flow through the conductor, converting chemical energy into electrical energy; and electrolytic cells, which have redox reactions that are influenced by … Read more
Adsorption Adsorption is a surface phenomenon that involves the accumulation of molecular species on the surface rather than within the bulk of a solid or liquid. Adsorbate is the substance that accumulates on the surface of another substance. For instance, … Read more
The major difference between a primary cell and the secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable. Before heading towards the discussion of differences between both … Read more
Physical adsorption, also known as physisorption, is a reversible phenomenon involving weak Van der Waals forces between adsorbate and adsorbent, whereas chemisorption is an irreversible phenomenon involving strong chemical interaction between adsorbate and adsorbent. S.N Physisorption Chemisorption 1. It is … Read more
Elements undergo chemical reactions to acquire a full outer shell of electrons, which will lead to a more stable energy state. This is accomplished through chemical bonding in which old bonds are broken and new bonds are formed. Thermal energy is … Read more
