... 9. Whenever you have a small atom and a large atom in a covalent bond, the large atom tends to hold onto the shared pair of electrons more tightly than the small atom. This results in a slight charge forming on each of the atoms. This is a polar molecule. State the most common example of a polar mol ...

... Laser light is emitted when a photon from a spontaneous emission between two energy levels induces stimulated emission of more photons. Laser light is monochromatic because all the photons have the same energy (E2 – E1) and hence the same frequency [(E2 – E1)/h]. Laser light is also coherent because ...
