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.

    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.

Android Versions Named After Sweet

Have you ever thought why are Android versions always named after sweet names ?? Everytime a new Android version is launched its name is kept after a sweet name. Many people have researched about this topic and many have asked Google also. Have you ever tried to find out the core reason behind this? If not then you would find the answer here . First of all let us first see what Google says about this : In 2008 i.e. the year when Android was launched a reporter asked the reason for the same. At that time Google said “It’s kind of like an internal team thing, and we prefer to be a little bit — how should I say — a bit inscrutable in the matter, I’ll say,” said Randall Sarafa, a Google spokesman. “The obvious thing is that, yeah, the Android platform releases, they go by dessert names and by alphabetical order for the most part."

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...

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...

The Inverse & Reciprocal TRIGONOMETRIC Functions

So, this is my second post on trigonometry. In this post we're gonna cover the reciprocal and the inverse Trigonometric functions. If you haven't seen my first post you should definitely view it as it covers the basics of Trigonometry The Reciprocal Trigonometric Functions The reciprocal Trigonometric function of Sine is Cosecant, of Cosine is Secant & for Tangent it is Cotangent. Cosecant (Csc θ = 1/Sin θ) or (Hypotenuse/Opposite) Secant (Sec θ = 1/Cos θ) or (Hypotenuse/Adjacent) Cotangent (Cot θ = 1/Tan θ) or (Adjacent/Opposite) We can also represent Tan θ in another way. As Tan θ = opposite/adjacent  & Sin θ = opposite/hypotenuse  & Cos θ = adjacent/hypotenuse ∴ Tan θ = Sin θ/Cos θ (The hypotenuses cancel out) As Cot θ = 1/Tan θ  So, we can also represent Cot θ as Cos θ/Sin θ.
