Study Notes
Chemical Foundation of Life
- Carbon is the chemical foundation for all life, forming the backbone of organic molecules.
- It has the unique ability to form four covalent bonds, allowing for diverse structures.
Isotopes
- Isotopes are variants of a chemical element with the same number of protons but different numbers of neutrons.
- They have identical chemical properties but different physical properties, particularly in terms of stability and radioactivity.
Electronegativity
- Electronegativity measures an atom's ability to attract and hold onto electrons in a bond.
- It plays a crucial role in determining the nature of bonds formed between atoms.
Types of Bonds
- Polar covalent bonds occur when two atoms with significantly different electronegativities share electrons unevenly.
- This results in partial positive and negative charges, contributing to the molecule's polarity.
Intermolecular Forces
- Intermolecular forces determine the behavior and properties of substances, such as boiling and melting points, solubility, and viscosity.
- They influence how molecules interact with each other in biological processes and material properties.
