Atoms of alkali metals are stacked in such a way as to form a body-centered cubic. There are 8 sections of an atom at the corner and one full one at the center. If you imagine stacking several of these blocks, you’ll realize that each corner is adjacent to seven others, so that each corner represents...

Atoms of alkali metals are stacked in such a way as to form a body-centered cubic. There are 8 sections of an atom at the corner and one full one at the center. If you imagine stacking several of these blocks, you’ll realize that each corner is adjacent to seven others, so that each corner represents 1/8th of an atom. The cell therefore represents 8(1/8) + 1 central = 2 atoms. 1. Write a formula for the mass of these two atoms in terms of molar mass and Avogadro’s number. m = 2 atoms(mole/(6.022 X1023 atoms)( M g/mole) = 2M/NA where M = molar mass NA= Avogadro’s number read less

de Broglie equation. the postulate of wave mechanics that a particle of mass m moving at a velocity v will have the properties of a wave of wavelength h/mv (de Broglie wavelength) where h is Planck's constant.

lambda = h/mv means that with any object that has a momentum (mv), there is an associated wave of wavelength lambda h is Planck's constant.

Hey Akshay try this for a change The positive rational numbers may be arranged in the form of a simple series as follows ( 1 / 1 ), ( 2 / 1 ), ( 1 / 2 ) , ( 3 / 1 ), ( 2 / 2 ), ( 1 / 3 ) , ( 4 / 1 ) , ( 3 / 2 ), ( 2 / 3), ( 1 / 4 ), ... Show that ( p / q ) is the [ ( 1 / 2 ) ( p + q - 1 ) ( p + q - 2 ) + q ] th term of the series. I see you like solving problems on mathematics so give it an honest try on your own Also to those boasting about years of experience in mathematics, please stop boasting about yourself before the rest of the teachers. If you are good, you are good and I do not doubt that. We all are here to help and not boast and this space is for questions only and not boasting. Hope you all keep this in mind.
As is visible, this relates to the partitioning of numbers without repetition. Let p+q = t Let us see the partitioning of 't' for 1st term 't' = 2 = 1+1 2nd term 3= 2+1 = 1+2 And so...
