Video transcript

Hello everyone. So in this video we're given four different statements. I was trying to see which one is true. So first let's recognize that the density of the diamond is at 3.5 g per centimeter. Cute. And for a graphite That's 2.3 grams per centimeter cubed. So both diamond and graphite are Covalin network solids with efficient packing arrangements in solid state. So basically what that means is that there's very low empty space in their crystal lattices. So we can see from these numerical values that our diamond is going to be more dense compared to our graphite. And flooring has more empty space in each ball and between balls compared to the diamond and graphite. So let's go ahead and write that or not is but has more empty space in each and quotes balls and between balls. So therefore we can say then that its density of the flooring will be considerably less. Then 2.3 g per centimeter cubed, which is the less dense one right here. So then the statement that is true is going to be a and this is going to be my final answer for this question. Thank you all so much for watching

Textbook Question

In their study of X-ray diffraction, William and Lawrence Bragg determined that the relationship among the wavelength of the radiation 1l2, the angle at which the radiation is diffracted 1u2, and the distance between planes of atoms in the crystal that cause the diffraction (d) is given by nl = 2d sin u. X rays from a copper X-ray tube that have a wavelength of 1.54 Å are diffracted at an angle of 14.22 degrees by crystalline silicon. Using the Bragg equation, calculate the distance between the planes of atoms responsible for diffraction in this crystal, assuming n = 1 (first-order diffraction).

Germanium has the same structure as silicon, but the unit cell size is different because Ge and Si atoms are not the same size. If you were to repeat the experiment described in the previous problem but replace the Si crystal with a Ge crystal, would you expect the X rays to be diffracted at a larger or smaller angle u?
