Which atom pulls the shared electrons more closely to itself in an O-H bond and why?

Oxygen is more electronegative than hydrogen, which means it will pull the shared electrons more closely to itself.
Very few elements will lose electron density to hydrogen in common chemistry.

Does hydrogren pulls on the shared electrons more than oxygen in water?
No, the opposite occurs. As the oxygen atom is much larger, it has a bigger 'pull' on the shared electrons, creating an uneven distribution of electrons known as a permanent dipole. No, Oxygen pulls the electrons more strongly than the Hydrogen, resulting in a partial negative charge on the Oxygen, and partial positive charges on the hydrogens.
What happens between atoms in covalent and polar covalent bonds?
covalent bonds is the sharing of electrons between two atoms. polar covalent bonds occurs when one atom is more electronegative than the other and therefore pulls the electron more closely to its atom (the electron is still being shared)
Do polar covalent bonds have a positive or negative charge?
Both. One side is positive while the other is negative. Taking H2O as an example, the hydrogen molecule pulls the shared electrons closer to itself, and further away from the two Oxygen molecules. This gives the Oxygen side of the H2O molecule a positive charge and the Hydrogen side a negative charge.
Why dont hydrogen and oxygen atoms share electrons equally in a water molecule?
Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
How is water molecule polar?
water molecule is polar due to higher electronegativity of the oxygen atom than hydrogen. The oxygen molecule pulls the shared pair of electrons partially towards itself resulting in the hydrogen atom having a small positive charge on it and the oxygen atom having a small negative charge, thus causing polarity.
Which atom pulls the shared electrons more closely to itself in an 0-H bond?
The oxygen, of course. The oxygen has a electronegativity of 3.5 to the hydrogens 2.2 negativity, so the electron tends to spend more time in the oxygen orbital giving that end hydrogen a slightly positive charge.

What kind of basic force pulls electrons close to the atomic nucleus?
The electric force pulls electrons close to the atomic nucleus. The protons in the nucleus have a positive charge, and so attract the negatively charged electrons.
Is NO nonpolar?
NO is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 ( bigger therefore pulls electrons harder) The electrons will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.

Both. One side is positive while the other is negative. Taking H2O as an example, the hydrogen molecule pulls the shared electrons closer to itself, and further away from the two Oxygen molecules. This gives the Oxygen side of the H2O molecule a positive charge and the Hydrogen side a negative charge.
Name three things gravity pulls down from earth?
The earth has gravity that pulls things to itself. The earth pulls human beings, the air we breathe, water, animals, trees, etc., to itself by its gravity.

Who discovered that earth pulls everything towards itself with a force?
Isaac Newton discovered that earth pulls everything towards itself with a force.It is called gravity.
What is a power sources job?
it pushes and pulls the electrons through the circuit
What is the job of the power source in the circuit?
it pushes and pulls the electrons trough the circuit
How does an ameoba move?
It extends a "false foot" and pulls itself.
