Difference between Covalent Bond and Ionic Bond: Comparison Table


Compare Covalent and Ionic Bonds

Covalent Bonds vs Ionic Bonds
(Similarities and Differences between Covalent Bonds and Ionic Bonds)

The chemical bonds are stable attractions between atoms, ions or molecules. The formation of chemical bond allows the formation of molecules or compounds. Chemical bonds are classified into different categories based on their formation and strength. Important types of chemical bonds recognized are Covalent bonds, Ionic bonds, Metallic bonds, Dipole-dipole interactions, London dispersion forces and Hydrogen bonds. The present post discuss about the Similarities and Differences between the Covalent bond and Ionic bond with a Comparison Table.

Covalent bond: A chemical bond formed by the sharing of electron pairs.

Ionic bond: A chemical bond formed by the electrostatic attraction between oppositely charged ions.

Similarities between Covalent Bond and Ionic Bond

Ø  Both covalent and ionic bonds are strong bonds.

Ø  Both are primary bonds.

Ø  Both bonds result in the formation of complex structures.

Ø  The formation of both covalent and ionic bonds results in the formation of more stable compounds than the original.

Ø  Formation of covalent and ionic bonds is exothermic.

Ø  Compounds formed by both covalent and ionic bonds will have net neutral charge.

Ø  Compounds with both covalent and ionic bonds are not malleable.

Sol vs Gel Comparison

Sol vs Gel
(Difference between Sol and Gel)

Sol, Gel and Emulsion are the different states of colloidal solutions.

Sol: The liquid state of a colloidal solution is called the sol.

Gel: The solid or semi-solid (Jelly like) stage of a colloidal solution is called the gel.

The present post discusses about the Difference between Sol and Gel.

Difference between Colloids and Crystalloids: A Comparison Table


Difference between Colloid and Colloid

Colloids vs Crystalloids
(Difference between Colloids and Crystalloids)

Colloids: Colloids are homogeneous non-crystalline substances containing large molecules or ultramicroscopic particles of one substance dispersed in a second substance. Colloids include gels, sols, and emulsions.  Unlike the suspension, the particles in the colloid do not settle and they cannot be separated out by ordinary filtering or centrifugation.

Crystalloids: Crystalloids are aqueous solutions of salts or minerals that can be crystallized.

Thus the main difference between colloids and crystalloids are their particle size. Both colloids and crystalloids are used as volume expanders and hence have immense applications in the medical field.

Difference between Simple Diffusion and Facilitated Diffusion: A Comparison Table


Difference between Simple and Facilitated Diffusion

Simple Diffusion vs Facilitated Diffusion
(Difference between Simple and Facilitated Diffusion)

Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration. Based on the presence or absence of facilitator molecules, there are two types of diffusion processes. They are (1) Simple Diffusion and (2) Facilitated Diffusion.

(1). Simple Diffusion: Here the diffusion occurs without the aid of an intermediary molecule such as channel proteins or carrier molecules.

(2). Facilitated Diffusion: Facilitated diffusion is the process of spontaneous transport of molecules or ions across a cell’s membrane via specific trans-membrane proteins.

Difference between Diffusion and Osmosis: A Comparison Table


Difference between Osmosis and Diffusion

Diffusion vs Osmosis
(Difference between Diffusion and Osmosis)

Diffusion and Osmosis are the two methods in membrane transport by which the movement of materials in and out of the cell takes places.

Diffusion: Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration. Example: When a scent-bottle is opened in a room, quickly the fragrance will spread to the entire room by diffusion of the molecules through the air.

Diffusion Example

Osmosis: Osmosis is a type of diffusion in which the solvent molecules move into the solution through a semi-permeable membrane. Example: Plasmolysis of a cell when it is placed in a sugar or salt solution.
