Study Notes
Bond Types
- Ionic bonds: Form between metals and non-metals through electrostatic attraction between oppositely charged ions (cations and anions).
- Covalent bonds: Form between non-metals by sharing electrons. These bonds form molecules.
- Metallic bonds: Join metals to metals, characterized by a "sea of electrons."
Chemical Formulas
- Sulfur Oxide (III): SOâ‚‚
- Iron (III) sulfide: Fe₂S₃
- Dinitrogen hexafluoride: N₂F₆
Valence Electrons
- Valence electrons are electrons in the outermost shell of an atom.
- The number of valence electrons determines bonding properties and electron configuration of different elements.
Molecular Geometry
- Molecular geometry describes the three-dimensional arrangement of atoms and lone pairs in a molecule.
- The geometry is determined by the number of bond pairs and lone pairs around the central atom. This affects the shape.
- Examples of molecular geometries and angles include:
- Linear (180°)
- Trigonal planar (120°)
- Bent (<120°)
- Tetrahedral (109.5°)
- Trigonal pyramidal
- Bent
