Describe each of the following models of the atom: the plum pudding model, bohr's model, and the wave mechanical model.

pulm pudding: Model of the atom proposed by J.J Thomson as a result of his work with cathode ray tubes. In it, the neutral atom contains negatively charged particles (electrons) scattered throughout a lump of positive charge like raisins in plum pudding.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
