An ionic bond. (a) Calculate the electric potential energy for a $\mathrm{K}^{+}$ ion and a $\mathrm{Br}^{-}$ ion separated by a distance of $0.29 \mathrm{nm}$, the equilibrium separation in the KBr molecule. Treat the ions as point charges. (b) What is the ratio of this energy to the ionization energy of the hydrogen atom?

So he was just looking at a few different definitions in the rounds off quantum mechanics and quantum chemistry. So firstly will look out the idea of wavelike properties. So there are three measurable properties off our wave motion. This is on amplitude, wave length and frequency. Next, we're looking out particulate properties. So a particle is a small, localized object or entity, which can be described several physical or chemical properties such as volume density and mass. So electromagnetic radiation can be described in terms of particles as well as waves. Let's just discuss here the experimental observations that drew this conclusion. So it was. The double slit experiment is a demonstration that light a matter can in fact display characteristics off both classically defined waves as well as particles.

In this question, we want to compare the content with land for an electron. Which that, too for proton. Okay. And then I want to also determine the value of the content we play for a proton. And the ratio uh the maximum content with like, shift or scattering by electron to get for scattering by a proton. Okay, so to solve this problem, okay. He content with playing. He is um H over M. C. Okay. So uh scenes the mass of a proton is greater than the mass of the electron. Okay, So the content with playing for proton will be less than the content with land For electronic. Okay, so the answer for parquet. Yes, last name. Okay. So and the explanation is by the formula of content with playing. Okay, then in part B uh we are shorter. Okay. And then Poppy went to find a content with playing for proton. So Amanda C. P. Is equal to H over M P. C. We're just putting their values. Okay? And then you use your calculator. Okay. And we're playing Yes, 1.38 Times 10 to the -15 m. Okay. So it's a much uh shorter with name. Yeah. Compared to that of electron, which is 2.43 and standard a negative child. Um, he does he he then Patsy want to find a ratio of the maximum content event shift by electron uh, to that by a proton. Okay. So the maximum something his name shift is good to to land at sea. He can calculate the ratio uh, um, so you take the ratio. The two doesn't matter. So the London see of electron if I buy the land at sea proton. Okay. H over M E C by H over MPC. Okay, so the asian see you cancers. Okay. So we have um, M P. D by by M E. Yeah. So you put in the aggressive proton and electron and calculated to be 1830. Okay, so this is the answer for pussy and that's all for this question.

Well, the answer is yes. Uh, the answer is yes. Overtones. Ragland can become shorter after collision is moving. Electrons will transfer kinetic energy to the photo on different a moment off collegian. So the answer is yes.

So we were just looking to define a few times. So fastly we've got the atomic spectrum. So the emission spectrum of elements consists of discrete lines in each element has a characteristic pattern of lines that is different from other elements. Next, we're taking a look at the photoelectric effect. So the phenomenon in which the mental service is able to emit electrons went electromagnetic radiation of sufficient energy are allowed to fall on them is considered the photoelectric effect extra considering matter waves. So matter. Waves are defined as waves associated with material particles, so these are not associated with electric and born and or magnetic fields. So unlike electromagnetic waves, they travel with different speeds. Is there associated with different particles, so the velocity is always less than the speed of light. Next, we have a Heisenberg uncertainty principle. So according to this principle, it is impossible to measure simultaneously the position of the velocity at the exact same time. Next, we're looking at the electron spin. The electron is in motion around the nuclear star rotates or spins about its own axis, which is known as the spinning of the electron. This can have the quantum number m s Next, we have Pauli's exclusion principle. So it states that no two electrons in an atom can have the same value for all for quantum numbers. Next, we have puns rule. This rule states that the electron pairing and all the doors of the same energy levels cannot take place unless all of the available orbital's of a given sub shall contain one electron each with a parallel spin. Thanks for having a little diagram. So the electrons filling in orbiters are known as orbital diagrams for the electrons. Next, we have electron charge density. So in classical wave, the amplitude of the wave corresponding to the wave function the intensity of the wave is wave. Function squared relates to the photon density the number of photons present in a region. So for an electron with the wave wave numbers square, this relates to electron charge density. Next, we just have our last one radial electron density. So this is a probability of the maximum electron density distributed. A particular distance from the nucleus is described by the radial electron density
