A chemical bond is an attraction that causes the formation of a chemical substance.
Most atoms are instable. Therefore, to become stable, bond to other atoms and perform the octet rule.
Ionic bonds are made through the attraction of oppositely charged atoms.
An Ionic bond is usually made of a metal cation and a gas anion.
Most Ionic bonds…Are Solid at Room TemperatureHave High Melting/Boiling PointsConduct electricity in a liquid
state or aqueous solution.
Ionic Bonds use Lattice Energy.
In a nutshell, it is how strong the bond of an Ionic Compounds is.
Single Bonds-A single bond is formed by mutual sharing of one electron.
Ex: Fluorine and Chlorine
Double Bonds-Double bonds are formed by a mutual sharing of 2 electrons
Ex: 2 Oxygen atoms
Triple Bonds-Triple bonds are formed by a mutual sharing of 2 electrons.
Covalent bonds fulfill the Octet Rule by sharing. The sharing of the electrons create the 8 valence shell needed to fulfill the Octet Rule.
A sigma is a single covalent bond.
Double bonds are one sigma and one pi
Triple bonds are one sigma and two pi
Bond Length and Dissociation Energy have a direct relationship.
As length decreases/increases, the energy decreases/increases.
The best way to describe a metallic bond is they are positive Ions drowned in a “sea of electrons”.
As mentioned before, the positive ion is covered with a “sea of electrons”. This sea allows for the passage of electricity but it also make this bond SUPER strong.
Because its bonds are SUPER strong, it takes a lot of energy (heat) to break it down. This explains the high melting point.
An alloy is a solid solution composed of 2 or more metals.
Since alloys are solutions, no chemical changes have occurred so that solution still retains properties of the metal it is composed of. Which is the main of making an alloy to enhance other metals by giving it properties of other metals.
