As Atoms make up everything that we see and touch it is not a surprise when you can see them they form together to make bonds. A chemical bond is a compound like metal, water, salt and oil. The Atom’s basically get together to make a stable structure. The different types of bonds are covalent, ionic and metallic bonds.
Plasma Spray like that from https://www.poeton.co.uk/standard-treatments/plasma-coatings is a good example of a chemical bond process. The super heated nickel in the spray is an example of a metallic bond. Metallic bonds lose electrons quickly so that their bonds tend to “float” in a sea of discarded electrons before they disappear. Alloy metals, even though they are made up of differing electrons, still have the free floaters in them.
It might surprise you to find that Salt is a type of metal. It has more positively charge electrons making them ions. Therefore salt is an ionic bond.
The strongest bond is that of the Covalent bond. This is where two electrons, one positive become attracted to each other and bond. One of the best examples of this is water. Water has hydrogen and oxygen working with the atom element to form into a solid state. If you add extremes of cold it will do this and freeze.
Ionic, covalent and metallic bonds compared
Atoms bond because doing so makes them more stable. An atom is most stable when its outer shell of electrons is full, so atoms with too few or too many outer electrons gain, lose or share them with other atoms, and new compounds are formed.
An ionic bond forms between a metal and a nonmetal. Electrons move from the metal atom to the nonmetal, creating charged atoms called ions. The metal becomes a positively charged cation and the nonmetal becomes a negatively charged anion. A covalent bond forms between two nonmetals, which share pairs of electrons. This is the type of bonding found in organic compounds containing carbon.
When two metals are involved, the result is a metallic bond, which occurs in pure metals and in alloys. The outer electrons are given up to a shared sea of electrons, leaving positive metal ions packed closely together in a lattice. Joining metals to other materials is difficult, which is why many industries rely on specialised metal bonding adhesives.
