- Properties of covalent molecules
- #^#. #^they are not hard or strong
- #t#. a #bweak force#b holds the molecules together
- #t#. many covalent molecules are a #bgas at room temperature#b,
- #t#teg Oxygen (O2) and Carbon dioxide (CO2)
- #t#. very little energy is needed to separate the molecules so
- #t#tthe #bmelting and boiling points are low#b
- #t#. they #bdo not conduct electricity#b as they do not have an
- #t#toverall electric charge
- #t#. a solid crystalline structure is #bbrittle#b and will shatter when hit,
- #t#. many molecular solids #bare insoluble in water#b, but soluble in
- #t#tother solvents
