How many magnetic substates (values of ml) does the electron d orbital have ? 1 2 3 4 5 6 7 8 9 0 Graph: How many magnetic substates (values of ml) does the electron d orbital have ? States in addition to their spectroscopic notation

If electrons did not obey the Pauli exclusion Principle then. The electrons in an atom would annihilate alongside the protons in the nucleus The electrons in an atom would all have the same energy The electrons would repel each other preventing the formation of atoms The electrons in an atom would have a continuous range of energies rather than lying in discrete levels Graph: If electrons did not obey the Pauli exclusion Principle then. Pauli Exclusion Principle No two electrons can occupy the same quantum mechanical state Actually true in consideration of all fermions (1/2 integer spin) Nothing so that do alongside Electrostatic repulsion Also true in consideration of neutrons Deeply imbedded principle in QM If all electrons were in the n=1 state all atoms would behave like hydrogen ground state No chemistry ? same properties

Black in addition to white photographic film is more sensitive so that blue than red light. Hence, there are. More photons in one joule of red light than in one joule of blue More photons in one joule of blue light than in one joule of red The same number of photons in one joule of red light as in one joule of blue Graph: Black in addition to white photographic film is more sensitive so that blue than red light. Hence, there are. Red/Blue E=hf Which light has higher frequency ? That photon has more energy Number of photons in 1J = 1J / Energy of 1 photon

Which is smaller ? An atom A light wave (visible spectrum) both are about the same Graph: Which is smaller ? Which is smaller? Smooth reflecting surfaces Atom must be smaller than wavelength of light Sizes?. Bohr radius 52.9 pm Visible light ? 400-700 nm Electron microscope ? typically a few pm

We first learnt that the sun has a magnetic field By measurements made from spacecraft near the sun By the direct effect of the sun?s magnetic field on magnetic compasses on earth Because anything that has gravity must have magnetism The effect the sun?s magnetism has upon the light we get from the sun. We have no knowledge of the sun?s magnetic field in addition to no present way so that get any Graph: We first learnt that the sun has a magnetic field Zeeman Effect Observe energy spectrum of H atoms Now ?add magnetic field Atoms have moving charges, hence magnetic interaction Spectral lines split (Pieter Zeman, 1896) Angular momentum has made small contribution so that energy (order 10,000th ) Fine Structure Discrete states as Ang.mom. quantized Nature, vol. 55 11 February 1897, pg. 347

If an electron was heavier spectral lines would be. shifted towards blue in addition to closer together shifted towards red in addition to closer together Shifted towards blue in addition to further apart shifted towards red in addition to further apart shifted towards blue in addition to same distance apart shifted towards red in addition to same distance apart closer together further apart unchanged Graph: If an electron was heavier spectral lines would be. H Energy levels Found an expression in consideration of E n = 2 n = 3 n = 4 Ionised atom E0 For transition Energy levels depend upon Electron mass in addition to n Spacing depends upon n values in addition to E0

When light emitted by a glowing gas is passed through a prism, a line spectrum is produced. A continuous spectrum will be produced if the gas is A mixture of several kinds of atoms Under low pressure Under high pressure None of these Graph: When light emitted by a glowing gas is passed through a prism, a line spectrum is produced. A continuous spectrum will be produced if the gas is Continuous Spectrum Each atom will have different set of atomic levels – electron orbits Different electron energy jumps Different photon energies Different line spectra More types of atoms, more lines Increase the pressure, atoms crowd each other Disturb each other?s atomic energy levels New orbits means new transition jumps More crowding , more energy jumps possible At high enough pressure have a continuous spectrum of energy transitions in addition to hence of photon energies

An atomic bomb was exploded inside a box that was strong enough so that contain all the energy released by the bomb. After the explosion the box would weigh More than before the explosion Less than before The same Nothing Graph: An atomic bomb was exploded inside a box that was strong enough so that contain all the energy released by the bomb. After the explosion the box would weigh E=mc2 Mass is turned into energy in explosion So it weighs less ? What is left of the bomb weighs less. However, energy in addition to mass are equivalent So, considering the energy also the total weight is the same

The protons in addition to neutrons in the atomic nucleus are held together by Gravity Electrostatic forces The weak nuclear force Magnetic forces The confining effect of the orbiting electrons None of the above Graph: The protons in addition to neutrons in the atomic nucleus are held together by A quark is a A type of lepton A composite particle made from mesons in addition to baryons A star that will become a black hole A galactical cluster A type of soft cheese

Which of the following do you consider so that be the most important benefit (if any) of the use of handsets in your lecture? Gives me an idea of how well everyone else is doing. Checks whether I am understanding the course material as well as I thought I was Allows me so that answer privately without others knowing how I voted. Allows lecturers so that identify problem areas Makes me think more about the course material during my lectures It’s fun It makes the lectures more interactive Other benefit Don’t consider there are any benefits Which of the following do you consider so that be the second most important benefit (if any) of the use of handsets in your lecture?

This Particular Journal got reviewed and rated by An atomic bomb was exploded inside a box that was strong enough so that contain all the energy released by the bomb. After the explosion the box would weigh More than before the explosion Less than before The same Nothing Graph: An atomic bomb was exploded inside a box that was strong enough so that contain all the energy released by the bomb. After the explosion the box would weigh E=mc2 Mass is turned into energy in explosion So it weighs less ? What is left of the bomb weighs less. However, energy in addition to mass are equivalent So, considering the energy also the total weight is the same and short form of this particular Institution is US and gave this Journal an Excellent Rating.
