Question

Why non-metals have low density?

Answer 1

Answer:

The bonding between their molecules are generally weak london or dispersion forces due to which there is less force of attraction. They also don't have definite packaging like metals have.

Answer 2

Answer:

Explanation:

Except mercury, most other non metals do have densities of less than 3. Lack of structure - hence being classified as a non metal. And inability to get packed as closely as normal atomic structure would allow are primary reasons why most non metals will have lower densities.
