Answer #1

Given edge length , a = 361.5 pm

                               = 361.5x10-10 cm                Since 1 pm = 10-10 cm

For a simple cubic structure, radius , r = a/2

                                                        = (361.5x10-10 )/2

                                                        = 180.75x10-10 cm

Therefore the radius of the copper atom is 180.75x10-10 cm
