Electron Shells and Energy
- Atoms have electron shells with a maximum number of electrons each can hold
- Inner shells fill before outer shells
- Atoms with incomplete outer shells are more likely to react
Atoms Interact and Form Molecules
- Chemical bonds link atoms in molecules
- Ionic bonds form when atoms gain or lose electrons
- Covalent bonds form when atoms share electrons
- Hydrogen bonds form due to attraction of a hydrogen atom to another electronegative atom
Chemical Bonds and Interactions
- Ionic bonds are formed by attractions between oppositely charged ions
- Covalent bonds are formed by sharing pairs of electrons
- Hydrogen bonds are attractions between a hydrogen atom (partially positive) and another atom with a high electronegativity (partially negative).
- Hydrophobic interactions occur in the presence of polar substances between nonpolar substances
- van der Waals forces are weak attractions between molecules
