H2O, dihydrogen monoxide, is a compound formed by sharing electrons. Water, or H2O, is a polar covalent bond which means that is has an unequal sharing of electrons.
Covalent Bond
Polar bonds
polar bonds
Electrons are shared between the atoms that are bonded. If there is an electronegativity difference between the atoms the electrons will be shared unequally.
Valence electrons
Polar Bond: A type of covalent bond between two atoms in which electrons are shared unequally. Because of this, one end of the molecule has a slightly negative charge and the other a slightly positive charge. Credit to: Wikipedia Resource
Covalent bonds occur when electrons are shared between nuclei. Example: methane, CH4; oxygen, O2They are called polar covalent bonds when the electrons are shared between nuclei unequally. Example: HCl (L not I)
In H2O the electrons are shared by the oxygen atom and two hydrogen atoms. Although there are two hydrogen atoms, the electro-negativity (or ability to attract electrons) of the oxygen is greater than the hydrogens, therefore the electrons are pulled greater towards the oxygen resulting in the oxygen becoming "negatively charged" this results in the molecule becoming what is known as a "dipolar molecule". This is what causes water to be attracted to each other as each molecule has a positive and negative pole. Answered by Mason Rawling-Jones (currently 15).

covalent compounds are said to be polar when shared pair of electrons are unequally distributed between the two atoms .

polar
None.H2S is a covalent compound, there are no ions as the electrons are shared between the hydrogen and sulfur.
Dative covalent bond, i think
A water molecule is polar because there is an uneven distribution of electrons between the oxygen and hydrogen atoms.
