Study Notes
Bond Polarity
- A bond is polar when there is a significant difference in electronegativity between the two atoms involved, causing an uneven distribution of electrical charge.
- Nonpolar bonds occur when atoms have similar electronegativities, resulting in equal sharing of electrons without a dipole moment.
Ionic Bonding
- Ionic bonding involves the transfer of electrons from one atom (usually a metal) to another (usually a nonmetal), creating charged ions.
- The electrostatic attraction between positively charged cations and negatively charged anions forms the basis of ionic compounds.
Covalent Bonding
- Covalent bonding is characterized by the sharing of electrons between two atoms, allowing them to achieve stable electron configurations.
- This type of bonding typically occurs between nonmetals and results in the formation of molecules.
Covalent Compounds
- The main focus of covalent compounds is the formation of stable molecules through shared electrons, often leading to complex structures with specific bond angles and shapes.
- Covalent compounds can be simple (like diatomic molecules) or complex (like carbohydrates and proteins).
Ionic Compounds
- The principal aspect of ionic compounds is the creation of stable crystalline structures through the attraction between ions, resulting in high melting and boiling points.
- Ionic compounds typically dissolve in water and can conduct electricity when dissolved or melted due to the mobility of ions.
