Answer:

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

Explanation:

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

  1. Most of the alpha particles get through film and can be detected by detector.  
  2. Around small portion of the alpha particle deflected at small angles.  
  3. 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 space of atom is empty and in center of atom , there is solid mass which is cause of alpha particles to come back. He gave the term nucleus to this solid mass.</u>
