I Wonder, By Jeannie Kirby [ poem ]

By -
                      I Wonder  I wonder why the grass is green, and why the wind is never seen ? Who taught the birds to build a nest,    And told to trees to take a rest ? O,  When the moon is not quite round, Where can the missing bit be found ? Who lights the stars, when they blow out,    And makes the lightning flash about ? Who paints the rainbow in the sky, And hangs the fluffy clouds so high? Why is it now, do you suppose, That Dad won't tell me , if he knows?                                                by  Jeannie Kirby

Discovery of Radioactivity / what is Radioactivity?

 The French physicist Henry Becquerel was engaged in furnishing a relation between X-rays and luminescence  exhibited by Uranium salts. Hindi video lecture dekhne k lie  👇👇👇   One day in 1896 by chance he wrapped a photographic plate in a thick black paper and placed a small crystal of potassium uranyl sulphate upon the black paper.Next day to his surprise he saw that the photographic plate had darkened at some places.  Becquerel concluded that the uranium salt had emitted a kind of ray which could penetrate the thick black paper, like X-rays.  Discovery of Radioactivity  After  thorough Investigation on the nature and the characteristics of the rays he came to the following conclusions  :--- 1. Uranium salts spontaneously emitted a kind of that could not be controlled by any physical or chemical condition.  2.  The ray could fog photographic plate wrapped in black paper and could pass through thin sheets of metal foil which are ...

Hello What's up..😊😊😊 [2]Azimuthal quantum numbers (l) It denotes the energy associated  with the angular momentum of the electron. it is also quantized and is indicated by— These values Indicate the sub-shell. The value of l vary from l = 0   to  l = (n -1) It  denotes actually    The shape of an electron orbital.     [3]  Magnetic quantum number (m). which Indicates Orientation of  electronic orbit in space under the influence of magnetic field. The value of magnetic quantum number ( m ) depends upon the value of (l).  it may have integral  values from -l to +l  including 0, [4]  Spin  quantum numbers (s). the electron always spins about its own axis either clockwise or anti-clockwise. Spin Quantum numbers gives the information  about the direction  of spinning of electron present in any orbitals. chat summary:
