A (very) polar covalent bond.
See the Related Questions to the left for more information about how to determine what kind of bond is formed between any two atoms.
Each hydrogen atom forms a double bond with the oxygen atom. Each H atom has one double bond and free electrons
The O atom has two double bonds (one with each H atom)
Since the atoms are sharing electrons, the bonds are considered covalent.
Also, since water molecules are polar (there is a positive charge at one end and a negative charge toward the other end) the bonds are also polar covalent bonds.

Imagine that the 4 dots next to each H atom are the electrons that are positioned around it.
The = sign represents the double bond Hydrogen has with Oxygen
The water molecule forms kind of a V shape in reality - not a straight line.
I am assuming you are talking about the bonds in water.
It is a covalent bond, and the structure is covalent molecular. This means that the Hydrogen atoms are sharing two electrons each with the oxygen atom. This makes sure that all atoms have a full outer shell. (each hydrogen has 2, and the oxygen has 8)
Covalent bonds usually result in gasses, but the bigger they get, the more likely it is to be a liquid. In water, there is a special other sort of bonding called hydrogen bonding, which results from the difference in electronegativies of Hydrogen and oxygen. This makes the bonds stronger, which makes it a liquid, even though it is a tiny molecule. Hope this helps
The bond is a covalent bond like in water.
The bond that forms between hydrogen and oxygen atoms is polar covalent.
Polar Covalent
Covalent bond
covalent bond between carbon-carbon and carbon-hydrogen
Covalent bond
Dipole-dipole attraction. It isn't really a bond that is formed, but an attraction between opposite charges. The only time polar molecules are attracted via a hydrogen bond (which isn't really a bond either) is if the hydrogen is attached to either a nitrogen (N), oxygen (O) or fluoride (F) atom.
covalent bond
A negative charge exists because of the electronegativity of oxygen.
hydrogen bond
There is little evidence of such a compound.
It depends what compound it is in. In water it is covalent. In trichloracetic acid it is ionic.
Water is not any kind of bond. Water is a molecule with polar covalent bonds occurring between the oxygen atom and two hydrogen atoms. Water molecules can form hydrogen bonds between them or with other substances.
A covalent bond.
A hydrogen bond.
Hydrogen bonding is usually formed between one lone pair of electrons of the oxygen atom of one water molecule and the hydrogen atom of another water molecule. Hydrogen bonding forms as a result of electro-negativity difference between oxygen atom and hydrogen, with oxygen being more electro-negative.
Single covalent bond :)
These are covalent bonds.
covalent bond between carbon-carbon and carbon-hydrogen
hydrogen, polar
Hydrogen bonds form between the partially positive hydrogen atoms of one water molecule, and the partially negative oxygen atom of another water molecule.
