The dipole in water is caused by the difference in electronegativity between Oxygen and Hydrogen. Oxygen is more electronegative than Hydrogen, so is better able to attract electrons towards itself. This results in the electron pair in the covalent O-H bond being more localised on the Oxygen atom, corresponding to less electron density on Hydrogen. Due to the additional electron density, the Oxygen is slightly negatively charged, while the lack of electron density on Hydrogen makes it slightly positively charged.
The reason for the difference in electronegativity is the number of protons in the nuclei of the two atoms. Hydrogen has a single proton, while Oxygen has 8, resulting in greater positive attraction for negatively charged electrons, outweighing the shielding effect of the full 1s shell of Oxygen.

What is positively and negatively charged in a water molecule?
it says oxygen acts negativw so most likely hydrogen on the bottom acts positive
What are the partial charges in a water molecule?
The Oxygen molecule and Hydrogen molecules have different electronegativity (due to position on Periodic Table). As Oxygen is more electronegative it draws the negatively charged electrons towards itself. This makes the hydrogen atoms more positive and hence the partial charges.
What is the oxygen atom of a water molecule?
Oxygen atoms in water molecules are the same as oxygen atoms in any other molecules; the definition of an oxygen atom is that it is an atom which has eight protons in its nucleus. Normally it has eight neutrons and eight electrons as well, but that can vary. It is only the eight protons which define it as oxygen.
What charge is a nucleus?
neutral
Do opposite charges attract each other?
If the atoms have opposite charges (positive to negative) they will attract. If the atoms have the same charges (positive to positive or negative to negative) then they will repel. You can look at the Law of Electric Charges to get more information on this.
Is oxygen atom has an overall negative charge with the hydrogen atoms having an overall positive charge?
All atoms have the same overall charge with the exception of ionization (electrons are lost or gained). since there are the same amount of protons and electrons in an atom, the negative and positive cancel each other out.
The hydrogen side of a water molecule is?
The hydrogen side of a water molecule is positively charged. This is because the oxygen atom in water is more electronegative than hydrogen, causing the electrons to be closer to oxygen, leaving the hydrogen atoms with a slight positive charge.
What makes hydrogen peroxide a polar molecule?
Hydrogen peroxide is a polar molecule because it has polar covalent bonds due to the difference in electronegativity between hydrogen and oxygen atoms. This causes an uneven distribution of electrons leading to a slight positive charge on the hydrogen atoms and a slight negative charge on the oxygen atoms.
What kind of bond is h20?
Water (H2O) is a polar covalent bond. This means that the atoms share electrons unequally, resulting in a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms.
Which water molecule has a partial positive charge?
In a water molecule, the hydrogen atoms have a partial positive charge. This is because the oxygen atom is more electronegative than hydrogen, pulling electron density towards itself and creating a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms.
What are water molecules polar with?
Water molecules are polar due to the unequal distribution of electrons between the oxygen and hydrogen atoms. The oxygen atom attracts electrons more strongly than hydrogen atoms, creating a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms.
What is the polarity of HCOOH?
Formic acid (HCOOH) is a polar molecule. It has a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms, which creates an overall dipole moment.
The oxygen atom in a water molecule has a slight negative charge?
Yes, the oxygen atom in a water molecule has a slight negative charge because oxygen is more electronegative than hydrogen. This causes the shared electrons to be closer to the oxygen atom, giving it a partial negative charge.
What makes the water molecule polar?
a water molecule is polar because their is an uneven distributive 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.
What is true of the bonds in a water molecule?
The bonds in a water molecule are covalent bonds, where electrons are shared between the oxygen and hydrogen atoms. These bonds are polar, with the oxygen atom being more electronegative, leading to a slight negative charge on the oxygen and a slight positive charge on the hydrogen atoms.
Is hydrogen covalent bonds?
Hydrogen bonds and covalent bonds are two completely different things. Covalent bonds share an electron, while hydrogen bonds (just for water molecules) act like magnets- the Oxygen atom has a slight negative charge and it "attracts" the Hydrogen atoms, which have a slight positive charge.
What are the events that happen in a water molecule?
In a water molecule, two hydrogen atoms are covalently bonded to an oxygen atom. This results in a polar molecule with a slight positive charge on the hydrogen atoms and a slight negative charge on the oxygen atom. These polar properties make water a versatile solvent and allow it to form hydrogen bonds with other water molecules.
