Bonds

[litty606]

How do we distinguish what element goes with each bond (single, double, triple)? Is it determined by group or period or other characteristics?

It is based on how many electrons each element needs to reach stability, or an octet. for example, since hydrogen only needs one more electron, it will most likely have a single bond with another element. since oxygen needs two more electrons, it will share two electron pairs with another element. since nitrogen needs three more electrons, it will share three electron pairs with another element.

The type of bond such as a single, double, or triple depends on how many electrons the elements need to be stable. A single bond shares one pair of electrons this is mainly between similar elements. A double bond shares two pairs and we have seen that mostly with carbon and oxygen. A triple bond shares three pairs and we have seen this with nitrogen. So basically the bond type relates to the element's position on the periodic table and their need for stability.
