Study Notes
Properties of Nonmetals
- Nonmetals are poor conductors of heat and electricity
- Nonmetals have high ionization energies and high electronegativities
- Nonmetals are generally brittle and cannot be easily molded or shaped
- Nonmetals have low melting and boiling points
Sulfuric Acid
- Chemical formula: H2SO4
- Used in the production of fertilizers, detergents, and lead-acid batteries
- Causes acid rain through atmospheric reactions
- Major industrial applications: fertilizer production, detergent manufacturing, oil refining, and wastewater treatment
- Contributes to acid rain formation through sulfur dioxide emissions
Sublimation
- Process of conversion of a solid directly into gas without going through the liquid phase
- Example: dry ice (solid carbon dioxide) sublimes at room temperature
Nonmetals vs Metals
- Nonmetals are typically poor conductors of heat and electricity, whereas metals are good conductors
- Nonmetals tend to gain electrons to form anions, whereas metals tend to lose electrons to form cations
- Nonmetals are brittle and cannot be easily molded or shaped, whereas metals are often malleable and ductile
