Rutherford Alpha Ray Scattering Experiment

Rutherford Alpha Ray Scattering Experiment


Hey, Guys, most of you might have heard about the alpha ray scattering experiment and if you want to know in detail about Rutherford's model and the experiment he conducted, this is the right place for you... But first:


Things You Must Know

Some basic information that will help you understand rutherford experiment properly:
  • Proton is a sub-atomic particle which is positively charged and has a mass of 1u.
  • Alpha particles are helium atom with a charge of +2 as they have lost 2 electrons.
  • Alpha particles have an atomic mass of 4u.
  • Gold is highly malleable and can be beaten into very thin sheets.




Experiment

Rutherford conducted his experiment in the following way:
  • Rutherford took a very thin gold foil and bombarded it with high energy alpha particles.
  • He placed a layer of zinc sulphide on the walls where the experiment was taking place because when alpha particles strike zinc sulphide layer, it results in illumination. This helped to determine the path of the alpha particles.





Observations

After the conducting the experiment, Rutherford observed the following:
  1. Most of the alpha particles passed without any deflection.
  2. Some of the rays faced minor and major reflections.
  3. One out of 12000 rays retraced its path. 



Conclusion

Various conclusions were derived from this experiment.
  • Most of the space inside the atom is empty as most of the alpha rays passed through the foil without any deflection.
  • There is a dense and heavy particle at the centre of the atom known as the nucleus which is positively charged.
  • Most of the mass of an atom is concentrated in this nucleus.
  • Nucleus in an atom is like a small cricket ball kept at the centre of a large cricket field.
  • All protons of an atom lie in the nucleus.
  • The positive charge of the nucleus is due to the presence of protons.



Rutherford's Model

He proposed that atom consists 2 parts:
  1. Nuclear Part: Containing the nucleus which comprises of protons and electrons.
  2. Extra Nuclear Part: Contains electron revolving around the nucleus.




Drawbacks

  • Rutherford could not explain the stability of the atom.
  • Rutherford could not explain the line spectrum of energy.
  • If an atom revolves around the nucleus in a spiral path it will radiate energy and in 10^ -8 seconds, the electron will collide with the nucleus, destroying the atom, but this doesn't happen as matter exist.

  3. Once done, a request for proposal has to be posted. Ensure it is not a copy of old outdated software and it has to be used for initiating a discussion and receiving a list of interested consultants. Each of the consultants has their own way of working process and it is desirable to ask for demos and case studies so as to find out whether they match your expectations.

Animal and Plant Cells

 Cells Cells are the basic functional, biological and structural unit of life. The word cell is a Latin word meaning ‘small room’. Cells are also known as building blocks of life.  The branch of science that deals with the form, structure, and composition of a cell is known as Cytology. All organisms around us are made up of cells. Bacteria, ameba, paramecium, algae, fungi, plants and animals are made up of cells.  Cells together form tissues. And tissue together makes an organ. History Of Cell The cell was discovered by Robert Hooke in 1665. He assembled a simple microscope and observed a very thin slice of cork under his primitive microscope. The cork was obtained from the outer covering of a tree called bark. Robert Hooke observed many little-partitioned boxes or compartments in the cork slice. These boxes appeared like a honey-comb. He termed these boxes as the cell. He also noticed that one box was separated from another by a wa...

High School Pedia

It is an initiative by some students to spread the light of knowledge to everyone and everywhere. It was started in the year 2015 and has grown rapidly in the past few months. By the means of this website, we try to provide information on every topic that we can reach up to. You can find different articles on this website. All these articles are written in simple language so that everyone can understand it and learn from it. We at High School Pedia believe in creative learning and this is the reason why we add our own edited graphical representations in every article. Once a very learned man said, “Knowledge increases by not keeping it to yourself but by sharing it with others”. And we follow the same motto “Share to Learn”. The team of High School Pedia tries its best to provide you with the best and original content. Unlike many other websites, High School Pedia is famous for its original and inspiring content.

2-D & 3-D GEOMETRY

2-D & 3-D GEOMETRY We all have some amount of geometry. We know that any line can be represented on the Cartesian plane. Any figure can be drawn on it. But can we represent a 3-d object on it. Yes we can. A Cartesian plane has 2 axis. While representing in 3-D we need to add a third axis. This axis does not come in between the axis or in the same plane. It appears to be coming out of the paper as we cannot represent a 3-d object on a 2-d surface. This new z-axis represents a line coming out of the screen. Before understanding 3-d geometry you need to imagine this axis coming out of the screen.  REMEMBER : all the three axis are perpendicular .i.e there an angle 0f 90 between them and they meet at the origin If you are unable to imagine you can take a thick book as an example. Any corner becomes it origin and the three edges as the three axis REPRESENTING 3-D GEOMETRY Like in 2-d geometry we represent the value of the different axis as (x,y) we use the sa...

Clock And Calendar

Hey guys ! It has been a very long time since we have learned something new. So now is the time we should start learning something new. Today I have selected two very basic but useful topics. If anyone of you is preparing for NTSE then these topics are must for your stage 2 Mental Ability. These are 2 very scoring topics which can get you good marks. So now let us begin with the learning.     Calendar So the first topic which are going to study is Calendar. Let us first know how will this help. by learning the tricks of Calendar you can find out the day for a given date. For example : the given date is 26th January,1950. By looking at the date you cannot tell the day but after a few calculations you will be able to. First thing and the basic thing for Calendar is "odd day". Now you must be wondering odd day means the third day or the fifth day but no. Odd day actually means the number of days left after a whole week is complete.. For better understandi...

REALLY Fast & Accurate Multiplication!!!(Vedic math)

Multiplication- as it should be done (Vedic math)                    Ever been thwarted by a math exam because of your slow or inaccurate multiplication, even when u know your trigonometry ratios. Here’s a method to uncomplicate your life and save you the invaluable time in your math exam Principle: This method mainly states multiply diagonally wherever possible and if not, multiply vertically Brief history (as if you wanna know😏!): This method was obtained from the Sanskrit Vedas, and therefore is considered a part of Vedic math but you don’t want me babbling about its history, so here is the method…   Lengthy Tutorial: 1)       You would first want to take out a piece of paper 😛 Ok fine, I get it… for real now 1)       For this example, we’re going to multiply 141 and 132 2) ...

Autonomous Cars

The Problem with Self-Driving Cars Every year, so many people die in car accidents, most of them caused because of the driver's negligence. Exorbitant amounts of money are spent just to fund awareness campaigns and stop people from “drinking and driving”. All of this after the fact that the technology for self-driving cars is in the last stages of development. Why are self-driving cars not the next big thing yet? Companies like Tesla, Uber and heck, even Google are racing to be the next innovator of autonomous cars. “This is stupid… Obviously, the cars are expensive.” See that’s the point, these cars are not ridiculously expensive (at least not for people who own an iPhone X). “Well then we obviously don’t have the requisite technology” That is partially true but trust me, the cars are way closer technology-wise than you may think. The biggest problem with autonomous cars is (insert drumroll) “A Moral Dilemma”. Disappointed? Just hear me out. Imagine ...
