The Raisins in a Bun Model done by JJ Thomson and the discoveries that followed.

In the 1890s scientist found that invisible rays jotic number 18 emitted when matter is hit with a jolt of electricity. Such experiments compound transmitting electric arcs amid twain ends of cathode ray tubes. more or less physicists discovered around substances that ad lib emitted invisible rays unheeding of electricity or each opposite type of energy. An typeface of these substances be: uranium and radium, which are relieve mavenselfd hot strongs. X-rays were a portion of the emitted rays that had the skill to cover dense objects. of import rays were denominate as rays that displayed high levels of energy.         They had the ability to, when covered with a saucer-shaped cathode, passion a piece of aluminum until it turned red. genus Beta rays were draw as being streams of particles knack in a magnetised field with a damaging charge. These beta rays were turn step forward to be minute in size and collectively except amounted to the mass of the sm eachest known molecule. They were all found to be analogous despite their origin. somewhat scientists speculated as to their purpose in the universe. Some though them to be the organic building block of the universe. They nurture for these beta rays was soon replaced by the name electron.         The English physicist by the name of JJ Thomson, discovered the electron in 1897. He was certain(prenominal) that either instalment consisted of electrons.

He deduced that since an atom contains a deaf(p) charge and consists of damaging electrons, there must be some other positively charged material indoors the atom to balance come forward the negatively charged electrons. He know that the electrons alone could non account for the mass of one atom due to their weightlessness weight. He deduced that this other material must account for well-nigh of the weight of the atom.         From these observations, JJ created a precedent that represented an...
