No, an oxygen atom is heavier than a hydrogen atom. The atomic mass of oxygen is about 16 atomic mass units (amu) while the atomic mass of hydrogen is about 1 amu.
In water (H2O), the bond holding one of the hydrogen atoms to the oxygen atom is a polar covalent bond. This bond is formed when the hydrogen atom shares its electron with the oxygen atom. The oxygen atom has a greater electronegativity than the hydrogen atom, creating a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atom.
Hydrogen bonding occurs between hydrogen and a highly electronegative atom such as nitrogen, oxygen, or fluorine. Chlorine is less electronegative than these elements, so it is not able to form hydrogen bonds with hydrogen. In hydrogen bonding, the hydrogen atom must be covalently bonded to a highly electronegative atom.
By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
Yes, a covalent bond between an oxygen atom and a hydrogen atom (O-H) is polar because oxygen is more electronegative than hydrogen. This causes oxygen to attract the shared electrons more strongly, leading to a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atom.
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).

No, it is inverse.

In a water molecule, the oxygen atom shares electrons with two hydrogen atoms, but it does not share equally since it has a stronger attraction for electrons than the hydrogen atom does, and the electrons therefore have a greater probability of being close to the oxygen nucleus than to the hydrogen nuclei. As a result, the oxygen atom has a negative charge. The hydrogen atoms are positively charged.
The dipole moment direction for methanol is from the oxygen atom towards the hydrogen atom in the molecule. This is because oxygen is more electronegative than hydrogen, causing an unequal sharing of electrons and creating a partial negative charge on oxygen and a partial positive charge on hydrogen, resulting in a dipole moment.
Yes, a covalent bond between an oxygen atom and a hydrogen atom (O-H) is polar because oxygen is more electronegative than hydrogen. This causes oxygen to attract the shared electrons more strongly, leading to a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atom.
A hydrogen only has one valence electron, while oxygen has 6.
Oxygen is more electronegative than hydrogen, so it tends to pull on the shared electrons in a water molecule more than hydrogen. This creates a slight negative charge near the oxygen atom and a slight positive charge near the hydrogen atoms in water molecules.
