Answer:
Ground state electronic configuration of oxygen atom is as follows - is 1s2 2s2 2p2x 2p1y 2p1z 1s2 2s2 2px2 2py1 2pz1
Ground state electronic configuration of hydrogen atom is 1s1 1s1
Explanation:
As per the Valence Bond Theory (VBT),
Ground state electronic configuration of oxygen atom is as follows - is 1s2 2s2 2p2x 2p1y 2p1z 1s2 2s2 2px2 2py1 2pz1
Ground state electronic configuration of hydrogen atom is 1s1 1s1
Considering the electronic configuration, H-O-H bond angle would be at 90 degrees as 2py2py and 2pz2pz are oriented 90° with respect to each other. But if the oxygen atomic orbitals is used directly then bond angle for water is 104.45° as per the VSEPR theory which states that 2s2s spherical orbit in oxygen can adjust the bond angle by creating new hybrid orbitals
