Water has 4 regions of electron density around the central oxygen atom (2 bonds and 2 lone pairs). These are arranged in a tetrahedral shape. The resulting molecular shape is bent with an H-O-H angle of 104.5°.
Water molecule is "made up of atoms of hydrogen and oxygen". When "two atoms of hydrogen" combine with "one oxygen" atom which is heavier that the hydrogen atoms, a water molecule is formed.
The molecule of water is electrically neutral. However, the molecule does have centres of positive and negative charges located at different locations. The "water molecules" have more inter-molecular spaces.
