An electron is present at an energy level with an energy of 16.32 x 10−19 J. During a transition to another level, 5.4 x 10−19 J of energy was absorbed. Which of the following is true about the present state of the electron? Answer Choices:

A. The electron moved down to an energy level and has an energy of 10.92 x 10−19 J.

B. The electron moved down to an energy level and has an energy of 21.72 x 10−19 J.

C. The electron moved up to an energy level and has an energy of 10.92 x 10−19 J.

D. The electron moved up to an energy level and has an energy of 21.72 x 10−19 J.

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
