Study Notes
Ionic and Covalent Bonds
- Sulfur dioxide (SO2) is classified as a covalent compound.
- In covalent bonds, molecules separate from each other when dissolved.
- Ionic compounds, like salt, break into individual atoms when they dissolve in water.
Electron Transfer and Compounds
- Nonmetals acquire electrons from metals due to their attractive forces.
- A compound is defined as a substance formed from two or more elements bonded chemically.
Types of Compounds
- Lithium nitrate (LiNO3) is identified as an ionic compound.
- Chlorine can form ionic bonds (by accepting electrons) and covalent bonds (by sharing electrons).
Properties of Ionic Compounds
- Ionic compounds possess a strong crystal structure, resulting in high melting points.
Compound Naming and Formulas
- The compound CH4 is correctly named carbon tetrahydride.
- Iron (II) sulfide is represented by the formula FeS.
- Aluminum fluoride has the chemical formula AlF3.
- The compound P2O5 is named diphosphorus pentoxide.
- The compound formed between lithium (1+) and oxygen (2-) is Li2O.
- MgCl2 is named magnesium chloride.
Valid Compound Matches
- Correct pairings of chemical formulas and names:
- Li3N corresponds to lithium nitride.
- SO2 corresponds to sulfur dioxide.
Additional Compound Formulas
- Dinitrogen trisulfide is represented by the formula N2S3.
Bond Definitions
- A covalent bond occurs between nonmetals, exemplified by compounds like water (H2O).
- An ionic bond connects metals with nonmetals, as seen in sodium chloride (NaCl).
