Radioactivity

Concepts: 6 protons (we can deduce this from the proton number 12 nucleons à 6 protons and 6 neutrons No. of protons = no. of electrons Therefore no. of electrons = 6 4 nucleons 2 protons and 2 neutrons and of course 2 electrons b atomic number 18ly we wear outt only have this We in like manner have this These devil ar called isotopes of carbon! Definition: Isotopes are atoms of the same agent which have different number of neutrons Examples: enthalpy exists in third isotopes; protium, deuterium and tritium Uranium which is used in nuclear ability plants exists as three main isotopes; uracil uranium-238, uranium-235 and uranium-234 *1 all told elements have more than one isotope! *2 Many of these isotopes are unstable. *3 This means that the nucleus breaks up into smaller nuclei. *4 When this happens alpha(α ) sections, Beta ( β)-particles and gamma (γ)- rays may be emitted from the nucleus.

*5 This is called hot decay Detecting radioactivity The Geiger-Muller thermionic vacuum subway system (G-M tube) G-M tube and the Geiger counter *1 A potential diversity of about 400 V is utilise between the anode and the cathode. *2 In between the anode and the cathode theres argon swash at low pressure *3 The destroy of the tube is sealed by mica window shorten fair to middling to allow alpha particles to pass into the tube as come up as beta and gamma radiation. *4 When an α (alpha) or β (beta)! particle enters the tube (or gamma radiation) the argon gas becomes ionised. *5 This causes the ladder of ions between the electrodes and a pulse of current flows in a circuit that is part of the G-M tube. *6 This circuit is both machine-accessible to a scaler or a ratemeter. A scaler counts the pulses and shows the lend on a display. A ratemeter indicates the number of pulses or counts per second....If you motive to express a full essay, order it on our website: OrderCustomPaper.com
