APF has been calculated based on the asumption that atoms spherical in nature and touching each ; is it

• true

• false

For a Simple Cubic structure, r is the radius of the atom, a is lattice parameter ; the relationship between r and a

• r = 0.5a

• r = a/3

• r = a/8

• r = a³/4

in 3D crystal structure classification, "I " represent

• BCC

• FCC

• SC

• None

basis is also known as

• motif

• motivation

• motion

• none
