<h2>Bombarded α-Particles on a thin Sheet of Gold
</h2>
Explanation:
- Rutherford Atomic Model is also known as " The plum pudding model"
- Rutherford’s in his experiment bombarded α-particles which are of high energy on a thin sheet of gold nearly 100 nm of thickness and observed the trajectory path of these particles after interacting with the foil of gold.
- He placed a fluorescent screen of zinc sulfide around the thin gold foil to study the trajectory path of the α-particles and its deflection.
- Most of the α-particles passed through the gold foil were not deflected as most of the internal space of the atom was empty.
- The result was that the positive charge of the atom occupies very little space.
Krista was most likely try to see how the amount of time she took to study reflected in her quizzes. She would most likely have higher scores if she studied longer. There is no information given on how her math scores are or how long she studies math so I can’t answer the third question. There’s no best way to study; everyone is different. Some rewrite notes and others make flash cards. You may like to be quizzed by someone. It just depends what works best for you.
