Why was niels bohr’s atomic model superior to all the earlier models? a. it proved that the atom was indivisible and therefore the smallest unit of matter. b. it showed how the electron could orbit the nucleus without falling into it. c. it was the first to show that the atom had no net charge. d. it used wave behavior to explain the positions of electrons around the nucleus.

Answer the correct option will be option B.

Explanation: this is how he showed the electron could orbit the nucleus without falling into it. This is so because he explained that the electron  revolves around the nucleus  in a fixed circular orbit with fixed energy and cannot occupy just any energy level which is defined as quantisation of energy.

option A is one of postulates given by Dalton in his Dalton's atomic theory which later proved to be wrong.

option C  it is one of the postulates given by the in J.J Thomson in his model of  an atom which was the first atomic model.

option D Schrodinger has used the wave nature to explain the position of electrons around the nucleus.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
