... fraction of a second; then it is immediately drawn back toward the nucleus, to its original orbital. As it returns to its original orbital, the electron releases the extra energy in the form of a photon, in this case a light photon. The wavelength of the emitted light depends on how much energy ... is released, which depends on the position of the electron. Different kinds of atoms will release different sorts of light photons meaning the color of the light is determined by what kind of atom is excited ... higher energy levels. When the electrons return to their original energy level, t...

... A) The resistance will be calculated in Ohms, the potential difference in volts, and the current in amps. Plan Apparatus too be used: 1. Power Pack (used to control the flow of electron through the circuit) 2. Amp metre 3. Voltmeter (used to calculate the value of resistance) 4. Resistance wire (the length of which will be used to change the amount of resistance) 5. Crocodile clips ... clip) 2. Attach the crocodile clips to the resistance wire at the appropriate place, so that the wire is 20mm long. 3. Turn on the power pack to allow the flow of electron through the circuit. 4. Ensure t...

... be separated through the application of an electric current. Electrophoresis was developed by Arne Tiselius. The process is used in medicine and biochemistry (science concerned with the organic and physical chemistry) to separate, identify, and measure the amount of various proteins. Electrophoresis is an analytical method frequently used in molecular biology (study of life processes) and medicine. It is applied for ... ...
