The diagram shows the arrangement of atoms in a particular crystal.
Each atom is at the corner of a cube.
The mass of each atom is 3.5 × 10–25 kg. The density of the crystal is 9.2 × 103 kg m–3.
What is the shortest distance between the centres of two adjacent atoms?
1 )
$3.8 \times {10^{ - 29}}m$
2 )
$6.2 \times {10^{ - 15}}m$
$3.4 \times {10^{ - 10}}m$
4 )
$3.0 \times {10^{ - 9}}m$
