Copper crystallizes in a face-centered cubic unit
cell with an edge length of 362 pm. What is the radius of a Cu atom in pm?
What equation do you use?
you have to think on a side.

Looks like to me four r radius= 1 diagonal
4r=sqrt2* 362pm
solve for r.
it says it's incorrect
To calculate the radius of cooper in face centred cubic unit cell there is a simple formula let a be the edge length then the formula is a/2rootunder2 or a/under root8 then according to question..r equal to 362/2root under 2 hope you understand
To find the radius of the copper (Cu) atom in picometers (pm), we can use the equation:
Radius = (√2 / 4) * Edge Length
In this case, the given information is that copper crystallizes in a face-centered cubic unit cell with an edge length of 362 pm.
Substituting this value into the equation:
Radius = (√2 / 4) * 362 pm
Now we can solve for the radius of the Cu atom.
