If you think of it in terms of time, the electrons always spend more on the oxygen. This creates polar bonds, and as the molecule is not symmetrical, it means that the whole molecule is polar.
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atomsAnswerA water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms. The negative pole is near the oxygen atom and the positive pole is between the hydrogen atoms.
The bond between water molecules is known as a hydrogen bond.
Electron Transport Chain. Molecules which carry electrons between photosystems, to build the hydrogen ion gradient to make ATP.
Water molecules are linked by hydrogen bonds.
Hydrogen bonding enables water molecules to bond to each other.
Hydrogen bonds form between water molecules and are relatively weak because there is actually no transferring or sharing of electrons. It would takes much less energy to break hydrogen bonds between water molecules than it does to break the molecules into oxygen and hydrogen.
The hydrogen bonds between water molecules are weak bonds. They do not involve the sharing or transfer of electrons.

In a water molecule, oxygen (which is a quite more electronegative than hydrogen), tends to attract electrons close to it, so it gets a residual negative charge, while hydrogen gets positively charged.That's the reason why water has a high boiling temperature, because water molecules establish electrostatic bonds, between the oxygen and hydrogen from different molecules, creating a kind of net of interactions, which make it harder to evaporate it.

The bond between water molecules is known as a hydrogen bond.
No Hydrogen is the weakest bond that can possible form between two molecules.
Hydrogen bonds are electrostatic attractions between a hydrogen atom, bonded to a more electronegative atom of one molecule AND a more electronegative atom of another molecule, but there is no sharing of electrons. In covalent bonding, atoms share electrons to form molecules.
Valence electrons
Water is polar, meaning the Hydrogen and Oxygen molecules in the water have an uneven distribution of electrons. This causes an attraction between the water molecules poles, like magnets, which draws them together. The water Hydrogen Bond also affects cohesiveness because each oxygen molecule in water has 2 lone pairs of electrons which can each form a Hydrogen bond with the hydrogen from another water molecule
