Oxygen is more electronegative than hydrogen, meaning that it likes to pull electrons towards itself more than hydrogen does. Since oxygen likes 2 electrons, it will bond to 2 hydrogen atoms, pulling 1 electron towards itself from each hydrogen. This produces a partial positive charge on the hydrogen and a partial negative charge on the oxygen.

The answer is D (in english)

Where is the majority of negative charge on the water molecule?

Water molecules consist of hydrogen molecules and oxygen molecules. Most of the negative charge comes from the oxygen molecules while the hydrogen molecules carry the positive charge.

Are the oxygen molecules positive or negative in water molecules?

They are negative. The H molecules are slightly positive. They get this way because of the "electronegativity" of oxygen.

Is H2O positive or negative?

Hydrogen is positive and Oxygen is negative.

How do water molecules attract other water molecules?

The Oxygen atom in water hogs electrons from the Hydrogen atoms, giving it a negative charge, and the hydrogens a positive charge. Because of this, water molecules have positive and negative ends. The positive Hydrogens in one molecule will attract the negative Oxygen in another.

Describe the polarity of a water molecule?

The oxygen molecule is slightly negative and the hydrogen molecules are slightly positive.

What is intermolecular hydrogen bonds?

A positive hydrogen atom has a tendency to attract more negative atoms like oxygen. Intermolecular bonds can be within molecules or between molecules.

What does it mean that water is polar?

It means that there is a positive and negative side to a water molecule. The positive ends being the hydrogen molecules and the negative end being the oxygen molecule.

Water molecules are polar with?

the oxygen side being slightly negative and the hydrogen side being slightly positive.

Where do hydrogen bonds form among water molecules?

In one water molecule, you have the slightly negatively charged oxygen side, and then you have the slightly positive hydrogen end. Because of this, the negative oxygen attracts positive hydrogens and vice versa in separate water molecules. This is where the hydrogen bonds are made.

What do hydrogen bonds do to water?

The molecules of water are held together by hydrogen bonding between molecules.These are electrostatic bonds (attraction forces between opposite charges) that hydrogen makes with the oxygen of neighbouring molecules. Hydrogen, when bonded to oxygen to form water molecules, is slightly positive and the oxygen in the water molecule is slightly negative. Hydrogen gets attracted to the neighbouring slightly negative oxygen atoms.This is great for life on Earth because small molecules the size of water tend to be gases but water is a liquid. It is a liquid due to the hydrogen bonding between molecules.

What is the polarity of water molecules?

Water molecules are slightly positive on the hydrogen end (the mickey ears) and slightly negative on the oxygen end (the mickey head).

What are the two charges in water molecules?

Water has two hydrogen atoms and one oxygen atom. The hydrogen atoms have partial positive charges and the oxygen atom has a partial negative charge.

Is the hydrogen in water positive or negative?

ttle positive as the Oxygen pullsup more electons from Hydrogen.

What explains why water molecules are attracted to each other?

Hydrogen Bonding and simply positive/negative attractive forces. The negative Oxygen atom of one water molecule is attracted to a positive Hydrogen atom of another water molecule.

How does the polarity of water make it a versatile solvent?

Because the positive hydrogen atoms of the water molecule attach with and dissolve the negative atoms of other molecules, and the negative oxygen atom attaches and dissolves the positive atoms of other molecules.

Why do water molecules have positive and negative poles?

Water(H2O) is a polar molecules due to the electronegative of oxygen (O). O draws the electrons towards it creating a negative charge over its atom. The hydrogen in comparison is positive in comparison.

What enables the water structure to form hydrogen bonds?

Water can form hydrogen bonds because of the polarity of its oxygen hydrogen bonds. In these bonds, oxygen has a partial negative charge and hydrogen has a partial positive charge. Because of this, the partially positive hydrogens on one molecule can form bonds with partially negative oxygen atoms in other water molecules. These intermolecular bonds are hydrogen bonds.

Why is water molecules described as a polar molecule?

It consists of a slightly negative oxygen atom and 2 slightly positive hydrogen atoms

Water molecules bind tightly to one another This is a result of?

Hydrogen bonding. The Hydrogen atoms and slightly positive and the oxygen atoms are slightly negative due to electronegativity and the hydrogens from one water molecule is attracted the the oxygen on other molecules

Polar molecules they attrack to other substances?

Polar molecules have unequal distribution of electrons. Water for example, oxygen is more electronegative than hydrogen so it will pull electrons towards itself, giving oxygen partial negative charge on it and partial positive charge on the hydrogen. A hydrogen bond forms between the partial negative charge on oxygen on another water molecule and partial positive charge on hydrogen on other water molecule.

What kind of bonds form between water molecules?

Attraction of the negative pole - oxygen, to the positive pole - hydrogen of a neighboring H2O molecule is called hydrogen bond

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.

What type of bond is found between water molecules?

Hydrogen bonds are found between water molecules. Hydrogen bonds are the electrostatic attraction (i.e. attraction between a positive charge and a negative one) between a slightly positive hydrogen atom and a slightly negative oxygen, nitrogen or fluorine. So in water, the attraction is between a slightly positive hydrogen atom and a neighbouring slightly negative oxygen atom. This is due to the electronegativity of oxygen, fluorine and nitrogen, which have a high electronegativity. In water, there are two bonds in each molecule, each linking one hydrogen to the oxygen atom. The electrons have less of an attraction to the hydrogen, and so the electron cloud is distorted in favour of the oxygen. So, as there are more electrons present near the oxygen relative to the hydrogen, the oxygen is more negative relative to the hydrogen, so causing polarity. Then, there is electorstatic attraction to neighbouring hydrogen or oxygen atoms.

What makes some covalent molecules polar?

Because of the unequal sharing of electrons. As in H2O, Hydrogen has a positive charge and Oxygen has a negative charge.

Do molecules always have a negative charge?

Molecules are neutral, they do not have an overall charge, although in many cases there will parts of a molecule which have a negative charge and other parts that have a positive charge (for example, in a water molecule, the oxygen atom has a negative charge and the two hydrogen atoms have a positive charge).
