Name and describe the 3 types of chemical bonds?

Answer 1

Ionic BondsIonic bonds form when two atoms have a large difference in electronegativity. A Ionic bonds often occur between metals and salts; chloride is often the bonding salt. Ionic bonds can typically be broken through hydrogenation, or the addition of water to a compound. Covalent BondsCovalent bonds often form between similar atoms, nonmetal to nonmetal or metal to metal. Covalent bonding signals a complete sharing of electrons. Covalent bonds are usually strong because of this direct bonding. Polar Covalent BondsPolar covalent bonds fall between ionic and covalent bonds. One atom becomes slightly negative and the other atom becomes slightly positive. Polar covalent bonds often indicate polar molecules, which are likely to bond with other polar molecules but are unlikely to bond with non-polar molecules.

Answer 2

Non-covalent bonds

Metallic bonding - a sea of delocalised electrons float between positive ions. This causes metals to be malleable and ductile, as you can distort them without their bonds being interrupted. They have high melting and boiling points due to strong electrical and thermal conductivity, as the electrons allow charge to flow freely through the metal. The electrons also reflect light, which is why metallic substances are so lustrous. Example: Copper

Ionic bonding - occurs between a metal ion and a non-metal ion. One ion is negative (anion) and one is positive (cation). These come together to form a compound with no overall charge. These compounds are typically crystalline solids at room temperature, and do not conduct electricity except when molten or in solution. Example: Ammonium Nitrate

Covalent bonds

Covalent molecular bonding - (often just called covalent bonding) This type of bonding is all about valency. A good example of covalent molecular bonding is water - H2O. The oxygen atom has six electrons, and as such needs two more to complete it's valence shell. Each hydrogen atom has only one electron. Both of the hydrogen atoms share their electron with the oxygen, so the oxygen has a full valence shell. In turn, the oxygen shares an electron with each hydrogen, so they have full valence shells of 2.

Covalent network bonding - If you're studying junior science, this type of bonding will be overlooked for the moment. It is similar to covalent molecular bonding, but is much stronger, and only occurs in graphite, diamond and silicon oxide (quartz).

Hope this helps!
