Chemical bonds are chemical compounds formed by the joining of two or more atoms. There are several types of bonds in chemical bonds, but this time will convey only 4 types of chemical bonds including ionic bonds, hydrogen bonds, covalent bonds and metal bonds. Happy listening!
Ionic Bonds
Ionic bonding is a type of chemical bond that occurs as a result of the electron handover of bonded atoms. Atoms that release electrons will be positively charged (cations), while atoms that accept electrons will be negatively charged (anions). One example of an ionic bond that is quite popular is the bond that occurs in the formation of sodium chloride salts, the reaction between NaOH compounds and HCl compounds that produce NaCl compounds.

| To further clarify what examples of compounds formed from the results of these ionic bonds. Some of the properties of compounds formed on the basis of ionic bonds are physically, compounds formed from ionic bonds at room temperature will be solid, have a somewhat brittle crystalline structure, have high boiling points and melting points, can dissolve at water solvents but not soluble in the type of organic solvents and in the solid phase do not conduct electric current, but when hydrolyzed in water will be able to conduct electric current. |
This is the physical character that is built by compounds with ionic bond types. Example Ionic:
NaOH + HCl → NaCl + H2O
Hydrogen bonding
A chemical bond of a hydrogen bond is a bond formed between the H element and atoms F, O and N. A substance that has more hydrogen bonds will usually boil faster when heated. In general, hydrogen bonds are divided into two type, namely intra-molecular hydrogen bonds and extra-molecular hydrogen bonds. Intra molecular hydrogen bonds are bonds between H atoms and F, O, N atoms that occur in a molecule, such as bonds between H atoms and O atoms in H2O compounds. While for extra molecular hydrogen bonds are hydrogen bonds that occur between compounds, for example between one H2O molecule and another H2O molecule.
Covalent bonds
Covalent bonds are bonds that occur as a result of the shared use of electron pairs by atoms that are bonded with each other. Covalent bonds consist of various types including single covalent bonds, double covalent bonds, triple covalent bonds, coordination covalent bonds, polar covalent bonds and non-polar covalent bonds. In general, compounds that have covalent bonds have several physical properties as follows: at room temperature it can be in the form of gases, liquids and solids, for solids which are usually soft but not brittle, have boiling points and low melting points, generally do not conduct currents electricity, dissolves in organic solvents and does not dissolve in water.
Metal ties
Metal bonds are bonds that occur because of the strong attraction between the positive ions of the metal against the valence electrons that move freely. Metal bonding causes the properties of metals including at room temperature in the form of solid except for metal Hg, hard but can be forged, a good conductor or conductor of heat, has a high boiling point and melting point and its physical appearance is shiny.
Those are some examples of bonds in chemistry that are usually widely used in various industrial applications and chemical laboratory works.
