Study Notes
Analytical Chemistry
- The primary focus of analytical chemistry is to identify and quantify the chemical composition of substances.
Applications of Analytical Chemistry
- Analytical chemistry has applications in various areas, including pharmaceuticals, biotechnology, environmental monitoring, and forensic science.
Qualitative Analysis
- Qualitative analysis in analytical chemistry involves identifying the components present in a sample, without determining their exact amounts.
Qualitative vs. Quantitative Analysis
- The main difference between qualitative and quantitative analysis is that qualitative analysis identifies the components, while quantitative analysis determines their exact amounts.
Sample Preparation
- Prior to analysis, sample preparation is often performed, which involves converting the sample into a form suitable for analysis.
Chemical Bonds
- Covalent bonds occur when atoms share their valence electrons with other atoms.
- Ionic bonds occur when one atom donates an electron to another atom.
Molecules
- The glucose molecule (C6H12O6) is a type of organic molecule.
- The oxygen molecule (O2) is a type of diatomic molecule.
Electron Configuration and the Octet Rule
- The valence electron configuration for stable atoms according to the octet rule is a full outer energy level with eight electrons.
- The electron-dot structure of an atom represents the valence electrons of an atom.
Noble Gases
- The primary role of the noble gases in the context of chemical stability is that they have a full outer energy level, making them unreactive.
Exceptions to the Octet Rule
- The main exception to the octet rule regarding stable atoms is that some atoms can have an expanded octet, exceeding eight electrons.
Electron-Dot Structure Abbreviation
- The abbreviation used for the electron-dot structure of an atom is Lewis structure.
