Three Major Chemical Bonds

Bonds is something that retains and holds on together with one another. There are three major chemical bonds and they are, Ionic, Covalent, and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons, they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl, because they are on opposite sides of the periodic table therefore that means that they are different and one has less valence electrons than the other. Na has 1 valence electron in its outer most shell and Cl has seven, it would need just one more to fill its outer most shell therefore it will create an ionic bond and the one with the most will take away what it needs from the one with the least.
The two kinds of covalent bonds are covalent and polar covalent bonds.The differences between Ionic and Covalent bonds are that ionic transfers the electrons with one another, covalent bonds share the electrons with each other and polar covalent bonds are in between covalent and ionic bonds which means that polar ionic bonds can either share or transfer the electrons, also polar covalent bonds are mostly around the atom instead of the other bonds that stay in
