Study Notes
Ion Definitions
- Ion: A charged atom resulting from the loss or gain of electrons.
- Anion: A negatively charged ion formed when an atom gains electrons.
- Cation: A positively charged ion formed when an atom loses electrons.
Specific Ions
- Fluorine (F⁻): An anion known for gaining one electron.
- Potassium (K⁺): A cation that forms by losing one electron.
- Chlorine (Cl⁻): An anion formed by gaining one electron.
- Magnesium (Mg²⁺): A cation that loses two electrons.
- Calcium (Ca²⁺): A cation that also loses two electrons.
- Sodium (Na⁺): A cation that loses one electron.
- Oxygen (O²⁻): An anion that gains two electrons.
General Concepts
- Metals typically give away electrons to form cations.
- Nonmetals tend to gain electrons, resulting in anions.
- Noble gases are chemically stable, preferring not to gain or lose electrons.
Chemical Rules and Principles
- Octet Rule: Atoms aim to have eight valence electrons for stability.
- Valence Electrons: Electrons located in the outermost shell of an atom.
Bonding Types
- Ionic Bond: A connection formed through the transfer of electrons between atoms.
- Covalent Bond: A connection formed by the sharing of electrons between atoms.
Electron Configuration Examples
- Atoms exhibit specific electron configurations based on their valence electrons:
- 1 valence electron: 1s²2s²2p⁶3s¹
- 2 valence electrons: 1s²2s²2p⁶3s²
- 3 valence electrons: 1s²2s²2p¹
- 4 valence electrons: 1s²2s²2p²
- 5 valence electrons: 1s²2s²2p³
- 6 valence electrons: 1s²2s²2p⁶3s²3p⁴
- 7 valence electrons: 1s²2s²2p⁶3s²3p⁵
