VIDEO Chemical Bond
A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds. The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bond" such as metallic, covalent or ionic bonds and "weak bonds" or "secondary bond" such as Dipole-dipole interaction, the London dispersion force and hydrogen bonding.
Since opposite charges attract via a simple electromagnetic force, the negatively charged electrons that are orbiting the nucleus and the positively charged protons in the nucleus attract each other. An electron positioned between two nuclei will be attracted to both of them, and the nuclei will be attracted toward electrons in this position. This attraction constitutes the chemical bond. Due to the matter wave nature of electrons and their smaller mass, they must occupy a much larger amount of volume compared with the nuclei, and this volume occupied by the electrons keeps the atomic nuclei in a bond relatively far apart, as compared with the size of the nuclei themselves.
In general, strong chemical bonding is associated with the sharing or transfer of electrons between the participating atoms. The atoms in molecules, crystals, metals and diatomic gases—indeed most of the physical environment around us—are held together by chemical bonds, which dictate the structure and the bulk properties of matter.
All bonds can be explained by quantum theory, but, in practice, simplification rules allow chemists to predict the strength, directionality, and polarity of bonds. The octet rule and VSEPR theory are two examples. More sophisticated theories are valence bond theory which includes orbital hybridization and resonance, and molecular orbital theory which includes linear combination of atomic orbitals and ligand field theory. Electrostatics are used to describe bond polarities and the effects they have on chemical substances.

What traits distinguish between covalent and ionic bonding?
ReplyDeleteAmong the ionic compounds and covalent compounds there is no clear dividing line. This is because ionic compounds can contain covalent properties and vice versa covalent compounds may contain ionic properties, covalent homopolar bonds
DeleteA compound is considered a covalent compound, when its covalent properties are more dominant, and vice versa a compound is considered an ionic compound when its ionic properties are more dominant.
The properties of ionic bonds (or electrocovalent bonds) are types of energy energy and chemical bonds that can form between metal ions with non-metals (or polyatomic ions such as ammonium) through electrostatic attraction forces. In other words, the ion bond is formed from the attraction between two different ions of charge.
For example on table salt (sodium chloride). When sodium (Na) and chlorine (Cl) join, sodium atoms lose their electrons, forming cations (Na +), while chlorine atoms receive electrons to form anions (Cl-). These ions then attract each other in a 1: 1 ratio to form sodium chloride.
Na + Cl → Na + + Cl- → NaCl
• The properties of Ionic Compounds Some of the essential properties of ionic compounds are as follows: the solution or melt may conduct an electric current, having high melting and boiling points, very hard and brittle, generally soluble in a polar solvent and insoluble in a non-polar solvent ( Baroroh, 2004).
• The properties of Covalent Compounds, among others, mostly show low melting points, at room temperature in liquid or gas form, dissolve in non-polar solvents and slightly soluble in water, slightly conductive to electricity, flammable and many smelly (Syukri, 1999).

Give me an example of dipole-dipole interaction!
ReplyDeleteAn example of dipole-dipole interaction can be seen in hydrochloric acid (HCl): the positive end of a polar molecule will attract each other with the negative end of another molecule and affect its position. The polar molecule has a resultant tensile force.
DeleteWhat is the difference between primary bond and secondary bond.?
ReplyDeletePrimary Bond
DeleteThere are three kinds of bonds that are grouped as primary bonds that are ionic bonds, covalent bonds, and metal bonds. These three bonds are called primary bonds because they are strong.
The secondary bond is a weak bond compared to the primary bond. The secondary bond is formed by the electrostatic attraction between the dipoles.
What are the electrostatic benefits for health?
ReplyDeleteThese electrodes have many benefits in everyday life such as for car painting, to reduce the dust level in the room based on microcontroller, for the photocopy machine, for laser printer
