Study Notes
Atomic Orbitals
- Atomic orbitals are regions of space around the nucleus that contain electrons.
- They are described by four quantum numbers.
Principal Quantum Number (n)
- Describes the electron's energy level.
- Higher values of n indicate higher energy levels.
Types of Chemical Bonding
-
Ionic Bonding: Occurs due to electrostatic attraction between oppositely charged ions.
- Cations are formed when an atom loses electrons (usually the least electronegative atom).
- Anions are formed when an atom gains electrons (usually the more electronegative atom).
- Most stable ions have a valence electron configuration similar to noble gases.
- The octet rule states that atoms tend to gain, lose, or share electrons to achieve a stable configuration with eight valence electrons (except helium, which has two).
-
Covalent Bonding: Involves sharing electrons between atoms.
- Can also occur in larger systems of atoms, like S8, P4, and diamond carbon.
