Rutherford was a British Scientist (Chemist). He performed many experiment using the particals. He performed the first experiment to split the atom. He is also known as the " Father of Nuclear Science. He won 1908 nobel prizes as a chemist. His famous experiment was " Rutherford's Atomic Model".
Rutherfords; Atomic Model
Rutherford performe a expeiment to know that how positive chage and negitive charge could coexist in any atom. He took a gold foil at size 0.00004cm. He through many alpha particals on this gold foil. Alpha particals were emitted by radioactive elements (Radium and Polonium).
He observer that the effects of alpha particals (a-particals) on a screen coated with zinc sulphide. He has proved that the Plum-puding model of the atom was't (not) correct.
Observations by Rutherford
- Almost alpha partical were passed by the foil whitout deflected.
- Many few a-particals (Alpha Particals) were deflected at a large angle.
- Very few partical are backed after hiting the foil.
Results of Rutherford's Atomic Model
- He observed that the volume is empty which is occupied by an atom because most of the particals were undeflectly passed by gold foil.
- The partical's deflection proved it that there is a center of charge. Which is consider as its nucleus.
- The nucleus is very hard it was proved due to complete rebounce back of few particals.
- As compare to the mass of an atom its nucleus is very small it was proved due to deflection of few particals.
- The electrons were revolved around the nucleus.
- The electrons in atom is equal to its protons.
- All fundamental particals in nucleus are known as necleous.
Defects of Rutherford's atomic model
- According to the clasical law the electrons being charged partical should release enegy whitout stoping. And they should fall in the nucleus.
- If the electrons release energfy contineously they should creat a spectrum, but line spectrem were observed.
Many scintists was asking him following questions to answer:
- Why are atoms stable?
- Why an atom give line spectrum?
- How can an atom collapes?
Conclusions
If you have any question about it then you can ask me in comments and If you think that this artical is best and usefull for students you should to share it to your friens and on your social media account as you can share. If you will give us good reponse then i will upload more articals as this.
