The two hydrogen atoms in water molecule (H2O) are connected to the oxygen via covalent bonds, which means the hydrogen and oxygen share electrons.(The hydrogen-oxygen bonds are primarily covalent rather than ionic.).hat type of chemical bond is there in water?   The two hydrogen molecules and the oxygen molecule in water are joined by covalent bonding where they share the electron.
The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge (from the presence extra electron share), while the hydrogens are slightly positive (from the extra un-neutralized protons). A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds. Consequently the electrons in the water molecule spend slightly more time around the oxygen atomic center and less time around the hydrogen atomic centers.
