Study Notes
Atoms and Bonding
- Atoms bond to achieve a stable electron configuration, usually having a full outer electron shell (octet rule).
- Molecules are formed when two or more atoms of the same or different types bond together.
- Compounds are formed when two or more different atoms bond together.
Types of Bonding
- Ionic bonding occurs between a metal and a nonmetal.
- Metals lose electrons, becoming positively charged ions (cations).
- Nonmetals gain electrons, becoming negatively charged ions (anions).
- Opposite charges attract, forming an ionic bond.
- Covalent bonding occurs between nonmetals.
- Atoms share electrons to achieve a full outer electron shell.
How Atoms Make Ionic Bonds
- Ionic bonding happens between metals and nonmetals.
- Metals lose valence electrons, becoming positively charged.
- Nonmetals gain valence electrons, becoming negatively charged.
- The opposite charges attract, forming the ionic bond.
- All elements want their outer shell to be full.
Valence Electrons and Stability
- Atoms gain or lose electrons to achieve a complete outer electron shell (stable configuration, usually 8 valence electrons).
- Valence electrons are the outermost electrons.
- This stable valence electron count means 8 electrons in the outer shell.
