    how come unshared electrons will be found on one side of a molecule of water instead of being spread out among the shared ones. (in the way that the molecule looks like it has to small legs instead of having one atom on each opposite side)

    Is metallic bonding stronger than ionic bonding?

    Allan, I think that Ionic bonding is stronger.

    im rather confused about molecular geometry. it seems that the only way to determine what the shape or whatever is is by looking at that chart… we don’t have to memorize it, do we??? :|

    & oh duh! yeah, britteny, youre right about ionic bonds being stronger.

    Hey guys – metallic bonding is the strongest, then ionic, then polar covalent, then nonpolar covalent, then intermolecular forces. But we’ll talk about that last part Monday.

    Josh, VSEPR stands for the Valence, Shell, Electron, Pair, Repulsion Theory.

    Valence Shell Electron Pair Repulsion is what VSERP stands for.

    is covalent bonding or ionic bonding stronger

    which is stronger covalent or ionic or mettalic

    Joey: The reason that some ABE formulas have the same shape have to do with the number of atoms bonded to the central atom and the number of unsharded pairs of electrons on the central atom. Some formulas hav the same number of atoms bonded and unsharded electrons, so therefore u have the same shape.

    A single covalent bondis a bond in which one pair of electrons is shared between two atoms.

    How can you tell if you need to use a single covalent bond or an double covalent bond?

  37.   Brandon hale Says:

    Bart, if one atom doesnt have eight electrons but the other atom that it is bonded to does , then you need to take a shared pair from the ‘happy’ atom and double it with the other to give them both eight.
