Detailed explanation-1: -There is no overall charge to a water molecule, but there is a slight positive charge on each hydrogen atom and a slight negative charge on the oxygen atom. Because of these charges, the slightly positive hydrogen atoms repel each other and form the unique shape.
Detailed explanation-2: -Hydrogen, the smallest of atoms has 1 outer electron, making it have a slightly positive charge (+1). The slightly negative charge of an oxygen atom attracts the slightly positively charged hydrogen atoms. Since oxygen needs 2 electrons, it can attract 2 hydrogen atoms.
Detailed explanation-3: -A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.
Detailed explanation-4: -Water is a Polar Covalent Molecule The unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles-a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).
