the angle between the hydrogen atoms in water (h₂o) is slightly less than expected for a tetrahedral shape. this is because of the\n○ extra electron repulsion from the lone pairs.\n○ atomic radius of the oxygen atom.\n○ additional repulsion of the shared electrons.\n○ extra repulsion of the hydrogen atoms.

Answer

Brief Explanations:

In a water molecule, oxygen has two lone - pairs of electrons in addition to the two bonding pairs with hydrogen. Lone - pair electrons have a greater repulsive effect than bonding - pair electrons. This extra repulsion from the lone pairs compresses the bond angle between the hydrogen atoms, making it less than the ideal tetrahedral angle.

Answer:

extra electron repulsion from the lone pairs.
