Why isn't water considered an ionic compound?

i know that one molecule of water has two hydrogen atoms covalently COVALENTLY bonded to a single oxygen atom. and and i also know that there is no ionic bond between oxygen and the hydrogen. but the question is that H+ and O- are both ions right so why does water have covalent bond except ionic bonds! please explain!! :)))) Thanx a lot!!!!

    Water has polar covalent bonds The oxygen keeps the electrons more of the time than the hydrogens.

    Pure water is a sharing electron situation. It does not ionize. It will not conduct until ions are added.

    2 Nonmetals tend to share, if unevenly, rather than totally transfer electrons.

    When H+ ions (acids) are added H3O- ions form, called hydronium ions

    Hydrogen can also form H- ion, hydrides

    Oxygen forms O^-2 ions, so H+ + O^-2 gives OH-, the hydroxide ion

    Really the differences between ionic bonding and covalent bonding are purely defined by the difference in the electronegativity between the bonded atoms. Oxygen = 3.5 Hydrogen = 2.1 the difference being 1.4. By definition to be ionic this number needs to be 2 or greater.

    The thing to understand is that even though a bond is considered covalent it can have some ionic character. The idea in defining covalent and ionic is so there is better understanding of where the electron density is around a molecule. A purely covalent bond will equally share the bonding electrons. In a purely ionic bond one atom gives up the bonding electrons to the other atom. In water more of the electron density is around oxygen than it is around hydrogen and so even though it is by definition a covalent bond it does have some ionic character.

    It is because, oxygen has an affinity to gain 2e- in order to fill the outer electron shell. (2p4) Therefore it COVALENTLY forms a separate bond with 2 separate hydrogen. But sometimes in chemistry, when we are studying acidity and alkalinity, we treat water as have an oxonium ion [H(3)O]+. This ion can act both as an acid by donating a proton (H+) and water as a base by accepting a proton (H+).
