Study Notes
Chemical Bonding
- Chemical bonding is the joining of two or more atoms to form molecules or compounds.
- It's driven by the atoms' desire to achieve a stable electron configuration, often resembling the noble gases.
- Types of chemical bonds include ionic, covalent, and metallic.
Ionic Bonding
- Ionic bonding occurs when a metal atom loses one or more electrons to form a positive ion (cation), and a nonmetal atom gains those electrons to form a negative ion (anion).
- The electrostatic attraction between oppositely charged ions forms the ionic bond.
- Ionic compounds are typically crystalline solids at room temperature.
- They have high melting and boiling points due to the strong electrostatic forces between ions.
- Examples of ionic compounds include sodium chloride (NaCl) and magnesium oxide (MgO).
- Ionic compounds conduct electricity when molten or in aqueous solution because the ions are free to move.
Covalent Bonding
- Covalent bonding involves the sharing of electrons between atoms.
- This sharing typically occurs between nonmetal atoms.
- Atoms share electrons to attain a stable octet configuration, similar to noble gases.
- Covalent bonds can be single, double, or triple bonds, depending on the number of electron pairs shared.
- Covalent compounds can exist as gases, liquids, or solids at room temperature.
- Their melting and boiling points are generally lower than those of ionic compounds.
- Examples include water (H₂O) and methane (CH₄).
- Covalent compounds often do not conduct electricity in any state.
Hybridization
- Hybridization is a concept used to explain the shapes of molecules formed by covalent bonds.
- It involves the mixing of atomic orbitals of different energies to form new hybrid orbitals.
- The new hybrid orbitals have different shapes and energies from the original atomic orbitals.
- The resulting shapes predict the bonding patterns of covalent compounds.
- Examples include sp, sp², and sp³ hybridization, which result in linear, trigonal planar, and tetrahedral molecular geometries, respectively.
- The different types of hybridization result in different bond angles and molecular shapes.
