Study Notes
Valence Electrons
- Located in the outermost energy level of an atom.
- Responsible for bonding and determining the chemical properties of elements.
Bonding Types
- Ionic Bonds: Formed when electrons are transferred from one atom to another, creating charged ions.
- Covalent Bonds: Created when electrons are shared between atoms, typically between elements close to each other on the periodic table.
Stability and Electron Requirements
- Atoms generally require eight electrons to achieve stability, a rule known as the octet rule.
- Stable configurations lead to the formation of chemical bonds.
Elements and Bonding
- Metals act as electron donors, typically losing electrons.
- Nonmetals function as electron acceptors, gaining electrons during bond formation.
Organic Chemistry
- Focuses on compounds that contain carbon, crucial for understanding biological processes and materials.
Ion Formation
- An ion results when an atom either loses or gains electrons.
- Cations are positively charged ions formed by the loss of electrons.
- Anions are negatively charged ions formed by the gain of electrons.
Molecules
- Defined as compounds characterized by covalent bonds, where atoms share electrons.
Chemical Formulas
- Convey the types and quantities of elements present in a compound.
- In ionic compounds like magnesium chloride, the overall charge balances to zero due to the attraction between positive and negative ions.
