Physical properties of non-metals are distinct and different from those of metals. These properties are influenced by the inner atomic structure of non-metals, which differs from the inner atomic structure of metals.
Non-metals exhibit properties such as:
Low melting and boiling points: Non-metals have lower melting and boiling temperatures compared to metals due to the weaker forces of attraction between their atoms.
High electronegativity: Non-metals have a higher electronegativity, indicating their ability to attract electrons more strongly. This property leads to a greater tendency to lose electrons, resulting in lower electronegativity.
Poor conductivity: Non-metals generally have lower electrical conductivity compared to metals. This is because the valence electrons in non-metals are more loosely bound to the nucleus due to the weaker forces of attraction.
High thermal conductivity: Non-metals have poor thermal conductivity, meaning they conduct heat less efficiently compared to metals. This property is attributed to the lack of free electrons and the presence of lattice vibrations in non-metals.
Variable density: The density of non-metals can vary greatly depending on the element. Non-metals with atomic sizes and electronic structures that allow for effective overlap of atomic orbitals tend to have higher densities, while non-metals with smaller atomic sizes and electronic structures that restrict overlap of orbitals tend to have lower densities.
Reactivity: Non-metals are generally more reactive than metals due to the ease with which their valence electrons can be lost. This reactivity can manifest as different chemical properties and reactions
