Study Notes
Ionic Bonds & Formulas
- An ion is an atom or group of atoms that has either a positive or negative charge.
- Ions form when atoms gain or lose electrons to become stable.
- Atoms are stable when their valence shell is full.
Cations & Anions
- A cation is an ion with a positive charge. It forms when an atom loses one or more electrons.
- An anion is an ion with a negative charge. It forms when an atom gains one or more electrons.
Ion Reactivity
- Metal atoms tend to lose electrons.
- Non-metal atoms tend to gain electrons.
Octet Rule
- Atoms form bonds to achieve a full valence shell of electrons, which promotes stability.
Ionic Compounds
- Ionic compounds have high melting and boiling points.
- They conduct electricity in water because they dissociate into ions with opposite charges.
- The ions are attracted to the electrodes.
- Ions form a crystal lattice structure.
Properties of Ionic Compounds
- Ionic compounds' properties include high melting and boiling points.
- They conduct electricity when dissolved in water or melted.
- The attraction between oppositely charged ions in ionic compounds makes them strong.
Electron Dot Diagrams
- Electron dot diagrams are used to represent valence electrons.
- The symbol of the element represents the nucleus and inner electrons.
- Dots are placed around the symbol to represent valence electrons.
- Electrons are not paired up until they have to be.
Ionic Bonding
- Ionic bonds involve the transfer of valence electrons from a metal to a nonmetal, creating oppositely charged ions.
- The electrostatic attraction between these charged ions holds the compound together.
- The charges on the ions influence the strength of the bond. Greater charge equals a stronger bond.
Ionic Bonding and Formulas Examples
- Specific examples of ionic bonding and how to determine ionic formulas are illustrated in the provided images/text, demonstrating the electron transfer process, resulting compounds, and properties.
