Do nonmetals have high or low boiling points? Do metals or nonmetals tend to form positive ions? Does oxygen have a higher electronegativity than hydrogen? Do nonmetals have luster? Are nonmetals reactive? What is the electronegativity of noble gases?
Explain why alcohols have higher boiling points as compared to their corresponding alkanes. Use appropriate chemical equations to explain this phenomenon. Briefly describe, why do elements in a given group have similar chemical properties? Give an atomic-level reason why ionic crystals a...
