Question

Mean distance between atoms is in the range of (a) 25 nm (b) 2.5 nm (c) 0.25 nm (d) 0.025 nm

Answer 1

Mean distance between atoms is in the range of: (c) 0.25 nm

- Mean distance is the distance between the nuclei of atoms in a substance.

- This mean distance is very large in comparison to the size of nucleus.

- Generally, it is of the order of a few angstroms, i.e, of the order of few tenths of a nanometer.

- So in the given options, most suitable option is (c)
