What even are the bonds of chemistry?? Well, a chemical bond is a mutual attraction between valence electrons and the nuclei of different atoms that attracts them together. The reason that they bond is to achieve noble gas configuration. All the atoms want to be stable, by having 8 valence electrons.
Covalent Bonding A covalent bond is when both a non-metal and a non-metal share electrons for them to both become stable. The characteristics of a covalent bond is that it has a very low melting point, doesn't conduct electricity in water, and that they aren't soluble in water. Again, this happens to follow the Octet Rule of 8. A simple way to put this would be a man and a wife have a total of 14 kids (some from previous marriages), each have 6 kids from their previous marriages and they share the 2 kids that they had together. An example of a covalent bond would be the two atoms share 2 valence electrons.
Ionic Bonding An ionic bond happens between a non-metal and a metal. Opposites attract in this bond, negative will equal out the positives. The characteristics of an ionic bond is that it has a high melting point, conducts electricity in a liquid, and is soluble in water. A simple way to put this would be a wealthy man (metal) has a lot of coats (electrons) that he needs to get rid of. There is a homeless shelter (non-metal) that is in need of coats, so he gets rid of the coats. Now both are happy and are equal. An example of a covalent bond would be the 1 electron in lithium and the 7 electrons in fluorine.
Metallic Bonding A metallic bond happens when 2 metals have an electromagnetic reaction between electrons in an electron sea. The characteristics of a metal bond is that it has a very high melting point, conducts electricity in a liquid, and isn't soluble in water. A simple way to put this would be that a bunch of boys and girls go to a dance and a boy and a girl hit it off. An example would be the electrons below.
