Ionic Bonds and Properties Quiz

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.
