In the molecule described, with an oxygen atom connected to two hydrogen atoms, where the oxygen atom has a negative charge and the hydrogen atoms have positive charges, the type of bond between the oxygen and hydrogen atoms is a polar covalent bond.
In a polar covalent bond, electrons are shared unequally between the atoms due to the difference in electronegativity, with oxygen being more electronegative than hydrogen, resulting in a partial negative charge on the oxygen and partial positive charges on the hydrogens.
