No, the hydrogen atoms in a water molecule carry a partial positive charge.

The oxygen atom is partially negative.

Hydrogen atoms are slightly positive in a water molecule while oxygen atoms are slightly negative. This is why electricity can flow through water.

hydrogen bonds. In water, the 2 hydrogen atoms are slightly positive while the oxygen is slightly negative. The two hydrogen atoms will align themselves at one end of the oxygen atom making that side of the molecule slightly polar positive and the side without the hydrogen ions slightly polar negative. Thus, when two H2O molecules are next to each other, the slightly negative side of one molecule is attracted to the slightly positive side of the other water molecule and this attraction is called a hydrogen bond.

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

A water molecule is formed by two hydrogen atoms and one oxygen atom which, when bonded, forms a polar molecule. Oxygen has a higher electronegativity than hydrogen, creating this polarity. So, the oxygen end of a water molecule is slightly negative.

The end with the two hydrogen atoms is positively charged. The oxygen end is negative.

The hydrogen atoms in a water molecule carry a partial positive charge. Hydrogen is happy being a proton anyway. The oxygen atom is partially negative because oxygen is so electronegative. This leads to Hydrogen bonding.

Not entirely sure right now, about 75%, but I believe that the side of the water molecule with the two hydrogen atoms is slightly negative and the oxygen atom side is slightly positive.

Hydrogen atoms are slightly possitive.

Molecules are attracted to each other because in a polar molecule, one or more atoms are slightly more positive or negative than the other atoms. The slightly more negative atoms are attracted to the slightly more positive atoms of other molecules, and vice versa. An example of the bonds that can be formed between molecules are hydrogen bonds (weak bonds between hydrogen atoms in a molecule. Ex: water).

The water molecule is polar. The oxygen and hydrogen atoms do not share the electrons equally. The larger oxygen atom tends to hold the electrons more closely than the hydrogen atoms. This causes the oxygen end of the water molecule to be slightly negatively charged, and the hydrogen atoms to be slightly positively charged. When a salt is added to water, the slightly positive hydrogen atoms attract the negative ions of the salt, and the slightly negative oxygen atom attracts the positive ions of the salt, causing them to dissociate and dissolve in the water.

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

H( slightly +) attracts Cl(-) Remember water is a polar molecule having a slightly positive end ( the hydrogen end ) and a slightly negative end ( the oxygen end ) because of of the difference in the atoms electronegativity.

Water molecules are polar because of the large electronegativity difference between the oxygen and hydrogen atoms. The oxygen atom is more electronegative than the hydrogen atoms. This causes the oxygen end of the molecule to have a slightly negative charge, and the hydrogen end to have a slightly positive charge.

A hydrogen molecule consists of two hydrogen atoms.

No, take for example hydrochloric acid (HCl). Because the two atoms are in a covalent bond and have different electronegativities, the chlorine atom is slightly negative and the hydrogen positive respectively. Therefore, one end of the linear molecule (because two atoms are always linear) is slightly negative, and the other is slightly positive, making it a polar molecule.

The water molecule does not have a negative charge. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. This is because the oxygen atom is more electronegative than the hydrogen atoms, and tends to hold the shared electrons more tightly than the hydrogen atoms.

There are two atoms of Hydrogen in the molecule.

A molecule with an uneven distribution of charge is said to be a polar molecule. A polar molecule, because of an uneven distribution of charge, basically has an "end" that is slightly more positive and another that is slightly more negative. Let's look at an example.The water molecule is a good example of a polar molecule. It's oxygen end is a bit more negative, and the end with the pair of hydrogen atoms on it is slightly more positive. That gives the molecule an overall "endedness" with a positive and a negative end.

Polarity. The oxygen end is slightly negative and the hydrogen end is slightly positive, thus water has all the properties we a familiar with and bonds easily and tentatively, one water molecule to the other.

There are two hydrogen atoms in a water molecule.

There re 10 hydrogen atoms in this molecule

There are three hydrogen atoms in an ammonia molecule.

because there are 2 hydrogen atoms in the molecule of hydrogen atoms

In a molecule of methane, the hydrogen atoms are slightly more positive on average than the carbon atom, but these are only moderately polar covalent bonds, not ionic ones.
