Title: What's the difference between a covalent bond and an ionic bond?
Post by: rlalonie28 on Sep 19, 2012
The only differences I know are that covalent bonds are bonds between a nonmetal and a nonmetal and they involve the transfer of electrons (?). And ionic bonds are bonds between a nonmetal and a metal and they involve the sharing of electrons(?). But what else is there because I feel like there's more to it than this.

Thanks =]

that's all i learned about it. is there anything else?i would like to know to.................

covalant is two non metals and ionic is non metal and a metal

you're halfway right.  A covlent bond is between nonmetals, however, it involves sharing electrons.  An ionic bond is between a metal and a non metal and involves the transfer of electrons.  There is nothing more to it than this unless you want to know about the properties of the different compounds, but that's not really important.

This statement is nonsense: "covalant (sic) is two non metals and ionic is non metal and a metal",  Gdawg Omizzle makes the same mistake.  It turns out that there are many metal-nonmetal bonds which have high covalent character.  For instance, take CuCl2.  The bonds in copper (II) chloride are actually more covalent than ionic.  

Actually, there is no difference.  It is simply a matter of degrees.  A 100% covalent bond consists of a pair of electrons which are shared equally.   As the bond becomes more polar, due to the electronegativity difference, the bond has increasing percent ionic character.  There are no 100% ionic bonds.  They simply don't exist.  Depending upon who you talk to, some would like to have a magic number for the electronegativity difference between ionic and covalent.  No magic number exists.

Therefore, we say that all bonds are covalent, except that some bonds are more polar than others.

More misconceptions from Aaron:  "A covalent bond is a weaker bond between electrons. and Ionic bonds tends to be stronger".   There are many covalent bonds which are stronger than some "ionic bonds".  And there are some "ionic bonds" which are stronger than some covalent bonds.  The whole issue of which kind of bond is stronger is ridiculous, for two reasons, as stated earlier, bond type spans an entire continuum of bonds, and bond strengths also span a wide range.  Interestingly enough the strongest of all chemical bonds occurs in diamond where the bonds are 100% covalent.

A covalent bond is a weaker bond between electrons.  and Ionic bonds tends to be stronger electronics also means a stronger charge of electricity.  It's sort of the reason why the batteries in our cars and cell phones tend to work because they use chlorine to eat up a metal within the battery which creates a charge.  An Ionic bond.
