The nature of the elements in the bond. Elements with a high difference in electronegativity have ionic bonds, elements with a small difference have nonpolar covalent bonds, and elements with no difference (if an atom binds to an atom of the same element) have nonpolar covalent bonds.
The more electronegative eleme
Covalent bonding involves two or more atoms sharing electrons. Coordinate covalent bonding is just an attraction that molecules have for other molecules based on the asymmetrical distribution of electrons in those molecules, creating negatively charged and positively charged regions (and hence, an attraction between the negatively charged regions of one molecule and the positively charged regions of another molecule).
The difference in electronegativity between the atoms that are bonded. A difference of more than about 1.7 indicates that the bond will be ionic. Health warning - this is only a rule of thumb.
Covalent compounds and molecular compounds are the same thing if I recalled correctly, just different terms of calling it. And covalent bonds are the bonds formed by the sharing of electrons between two atoms, and they are the strong forces of attraction WITHIN the molecule.Please do not get it mixed up with the weak van der Waals' forces that is found BETWEEN molecules and is caused by a temporary shift of electrons to one side of the molecule, resulting in a slightly positive/negative end.
polar covalent - use the electronegativity difference
In a single bond there is only a strong sigma bond on the other hand in multiple bond there is a sigma & one or two pi bond, weaker than sigma, which provied addition reactions in a molecule.
Covalent bonding involves two or more atoms sharing electrons. Coordinate covalent bonding is just an attraction that molecules have for other molecules based on the asymmetrical distribution of electrons in those molecules, creating negatively charged and positively charged regions (and hence, an attraction between the negatively charged regions of one molecule and the positively charged regions of another molecule).
Types of bonding: ionic (in salts), covalent (in organic compounds), metallic (in metals).
Covalent bonding is formed generally between nonmetals.
Iodine molecule has covalent bonds.
because there is no electronegativity difference between the two oxygen atoms.
The electronegativity difference between the bonding atoms is concerned to determine it ionic behaviour.
The difference in electronegativity between the atoms that are bonded. A difference of more than about 1.7 indicates that the bond will be ionic. Health warning - this is only a rule of thumb.
Ionic and covalent bonding involve electrons. Ionic bonding involves the loss and gain of electrons, form ions. Covalent bonding involves the sharing of electrons.

electrons are shared between one or more atoms
