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:
Most of the alpha particles get through film and can be detected by 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 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>
This was Ernest Rutherford’s gold foil experiment. He used radioactive alpha particles as a part of the experiment and discovered that there was a densely packed, positively charged nucleus in atoms with electrons that were spread out in spaces between nuclei.
It all depends on the flower. Flower plants are capable of sexual reproduction. However, they vary on whether they can reproduce both ways, or only sexually.
The most common sites of injury are the cervical and thoracic areas. SCI is a common cause of permanent disability and death in children and adults. The spine has 33 vertebrae.
