Types of Bonds

[KarenaKaing_1D]

How do you know what type of bond an element has? For instance, why does Flourine have only a single bond with 6 electrons outside in its Lewis structure? Why can't it have a double bond with 4 electrons outside?

[Hyelim Chun 1D]

Because fluorine has 7 valence elections, it only needs one more electron to complete the octet. Therefore, when fluorine bonds with other elements, it is likely to form a single bond rather than double to get one more electron.

[Rambod Meshgi 3J]

Well fluorine starts with 7 valence electron so it shares 1 and has 6 unpaired electrons and a single bond, reaching a full octet. In a bond each electron comes from a different atom a fluorine couldn't have 4 unpaired electrons and a double bond because it would have to share two electrons with an atom that's not sharing any electrons back. In addition fluorine is extremely electronegative it would never want to share that many of its electrons.

Is a heteronuclear atom with an electronegativity difference >2 but <1.5 considered mainly a covalent or ionic bond?

[Ulysis Baal 4J]

An element does not have a set "bond" that it carries around. The type of bond it has with other (or the same type) of elements will depend on its electronic interaction with the other element(s). Usually all atoms in a molecule strive for an "octect" to achieve the greatest stability, so their electrons and bonds are arranged with respect to this rule
