Study Notes
Types of Chemical Bonds
- Ionic Bonds: Form between a metal and a non-metal atom. The metal donates an electron to the non-metal, creating positive and negative ions. The charges balance, resulting in a neutral compound. Formation depends on the number of electrons in the outermost shell.
- Covalent Bonds: Formed between non-metal atoms. Atoms share electrons. Covalent bonds are generally stronger than ionic bonds.
- Non-polar Covalent Bonds: Occur when atoms have similar electronegativity, sharing electrons equally.
- Polar Covalent Bonds: Occur when atoms have different electronegativity, leading to unequal electron sharing.
Additional Types of Bonds
- Metallic Bonds: Occur between metal atoms, involving a "sea of electrons" shared among the atoms.
- Hydrogen Bonds: Form between hydrogen atoms and other atoms with a dipole (having a positive and negative end).
Solutions and Mixtures
- Solutions: Homogenous mixtures of one or more solutes dissolved in a solvent. Individual components cannot be visibly distinguished. Examples include sodas, seawater, air, and metal alloys.
- Ionic Compounds in Solution: When an ionic compound dissolves in a solvent, it breaks apart into its component cations and anions.
- Classifying Solutions by State of Matter: Solutions can be categorized based on the state of the solute and solvent. Examples include solid-solid (bronze), liquid-liquid (hand sanitizer), gas-gas (air), solid-liquid (sports drinks), liquid-gas (sodas), and gas-solid (hydrogen gas and platinum).
- Heterogeneous Mixtures: Mixtures that are not homogenous.
- Suspensions: Heterogeneous mixtures that separate into layers over time (e.g., sand in water).
- Colloids: Heterogeneous mixtures that do not separate into layers (e.g., milk).
