Question

List of important formula in solid state

Answer 1

there are many formulas in solid state
like d=m/v

Answer 2

Hey dear,

● Important formula in Solid states -
# Packing fraction -
Packing fraction = Volume occupied by particles / total volume of unit cell

# Radius ratio wrt voids -
Triangular voids, 0.155 < r+/r- < 0.225
Tetrahedral voids, 0.225 < r+/r- < 0.414
Octahedral voids, 0.414 < r+/r- < 0.732
Cuboidal voids, 0.732 < r+/r- < 0.999

# Density of cubic crystal -
Density = Z.M / a^3.Na

# Crystal structures -
In Simple cubic, Z = 1, r = a/2
In FCC, Z = 4, r = a/2√2
In BCC, Z = 2, r = √3a/4

Hope this helps you...
