Is the (200) plane of fcc crystal structure(the plane parallel to the face of unit cell and passing through the body centre of it) a close packed plane?
A close packed palne is a plane where the neighbouring atoms touch each other. Eg: (100) of simple cubic (111)of fcc
But in thiscase when i draw the plane, i got four half circles on the middle edges of the square, touching the atoms on each side. But, they donot touch the atom infront. So, i have a doubt whether it is close packed? Please explain.
