Answer: The components of a pure substance are single elements or compounds instead of a mixture of compounds.
Explanation: Pure substance consits of a pure type of particle.
All elements and compounds that are considered as pure will have fixed boiling point and melting point.
Answer:
A high difference in electronegativity will be present in ionic compounds since the electrons are transffered from the element less electronegative to the element more electronegative.
A small difference in electronegativity is present in molecular compounds (covalent bonds). None of the elements is strong enough to attract the electrons so the electrons are shared.
