That isn't the atomic packing factor. That's a lattice parameter in terms of atomic radius.

Yes. But from here to PF is just simple division.

That is bcc's atomic radius for cubic lattice And atomic packing factor for it is , 0.68 according to my perception

Thank you! Really helpful :)

"And that how you find a, a is the lattice perimeter which if cubed is the volume of the cell." i think saying "a" is the APF is misleading sort off.

gorgeous professor :3

Thanks...... You are a real godess (hoor from junnah)❤

For anyone that comes by: APF = (number of atom volumes inside a cell) * (atom volume) / (volume of a cell) So for FCC we got: (number of atom volumes inside a cell) = 4 Its one eighth of a volume in each corner and half a volume in each face (atom volume) = volume of a sphere of radius equal to the atomic radius (R) (volume of a cell) = a^3 with a = (4/sqrt2)*R That gives APF = .74

Valentín Finozzi Good work but this video is for a body centered cubic

THANK YOU FOR THE TUTORIALS!!!!!!!!!!!!!!!!!!!!

Thanks, i got it in the first time :)

Thanks for the video

Okkk... That's half through the problem and now actually we have to put the values in the formula of the APF @Parisa Najafi 😅 ..though it was helpful 😃

Extremely beautiful mam

I dont catch the part "4r^2", is it found by dividing the diagonals into four parts, where atoms are touching, and the center of the central atom?

Thank you

a is the side of the unit cell which you cube to get Vc (volume of unit cell). APF =Vs/Vc where Vs is volume of spheres. 2 atoms in BCC so 2 x vol of sphere. APF =0.68

where is the a power 2 coming from?

looking good

THANKS

Nice video

Beautiful 💘

That is not atomic packing factor.You have shown the relationship between atomic radius and edge length of a BCC crystal structure.But meanwhile thanks for the video.

i need a tutor like her

I am Indian 🇮🇳.. U are very quite and lovely.

Very nice explaination

yep. i think i fell in love.

im right there with ya my dude

This is edge length of a BCC unit cell. It isn't the APF, since more steps are needed to get it. From the edge length, we can find the unit cell volume. Then, we divide the total atom volume by that. Good video but it's a bit misleading...

thanks

Thanks 🥰🥰🥰🥰

if i have teacher like her

i came here to do only HCP now i'm doing whole course again

Hello sir What is Packing Factor

@victorogunjimi2206

It's the percentage of the unit cell that is occupied by atoms. What is left of the unit cell is void.

Good description but not as in the title

You are too intelligent and beautiful

She is very cute

Lattice parameter

You are very Hort mem

Feel like some kinda angel teaching APF .. she talks like angel oh lord i fall in love

This half of solution

its not apf u just related a with r

Mam u looking beautiful

That's isn't apf honey

this is side of BCC not APF.... u hve tot do more to find APF

how cute you are

Maybe the problem in me 😢

Am I here to study something 🤔🤔🤔 . By the way thanks for the name ☺☺☺☺

Change the title please. This is not atomic packing factor. This is a lattice parameter in terms of atomic radius. Your title is misleading.

Totally wrong,,,,,, how do you add a2+a2+a2=3a2,,,,, You should apply Pythagoras Theorem. Thereby you can get value... Or else don't mislead the people

It is body diagonal (3D) so it's right.
