Water has a bent molecular structure. The two hydrogens are attached to the Oxygen with single bonds to look like this
H - O - H
But, it does not stay straight, it bends.
The oxygen has 6 valence electrons and thus needs 2 more electrons from 2 hydrogen atoms to complete its octet. This then leaves two lone electron pairs that are not bonded to any other atoms.
The 2 lone electron pairs exert a little extra repulsion on the two bonding hydrogen atoms to create a slight compression to a 104.4 (or 105) degree
bond angle.
Basically, the two lone electron pairs try and get themselves as far apart as possible, but the two hydrogens want to stay as far apart as possible to, so the structure bends exactly 104.4 degrees, but for all intensive purposes, the angle is 105 degrees.

I don't know the angle between them, but I do know how they are attached. There is an electron (I forget if it's more than one or not) from one of them (I forget if it's from the hydrogen or the oxygen) that begins to orbit both, and this tiny change in atomic structure holds the atoms together with the incredible strength that gives water its awsome surface tension. For the stuff in parentheses, research ionic bonds (and covalent bonds, to learn the difference), especially as pertinent to water.

The hydrogen bond is particularly a particular case of dipole forces. A hydrogen bond is the gorgeous rigidity between the hydrogen linked to an electronegative atom of one molecule and an electronegative atom of a diverse molecule. many times the electronegative atom is oxygen, nitrogen, or fluorine, which has a partial adverse fee. The hydrogen then has the partial helpful fee. Hydrogen bonding is many times better than generic dipole forces between molecules. of path hydrogen bonding isn't almost as sturdy as generic covalent bonds interior of a molecule - that's barely some million/10 as sturdy. this continues to be sturdy adequate to have many important ramifications on the properties of water.

The bond angle is 120 degrees. Additional electrons on the oxygen atom occupy the 3rd space.

They are attached by a covalent bond. Not sure about the angle.
