svetlana [45]

Explanation:

Rutherford conducted an experiment in which he took a thin gold particle film on which he passes alpha- particles. He noticed that:

  • Most of the alpha particles get through the film and can be detected by the detector.
  • Around small portion of the alpha particle deflected at small angles.
  • A very very few alpha particle (approximately 1 out of 1 million alpha particles) just retraced their path which means come back from the center.

He concluded that:

<u>Most of the space of the atom is empty and in the center of the atom , there is solid mass which is the cause of the alpha particles to come back. He gave the term nucleus to this solid mass.</u>

Oxygen is broken down or dissolves in a thin film of fluid in the alveoli, surprisingly in normal breathing liquid composed of dissolved oxygen is involved. Evidently respiratory gas must be able to dissolve in this liquid and in concentration required to keep the partial pressure necessary to power diffusion.
