Study Notes
Characteristics of Ionic and Covalent Bonds
- Ionic compounds appear as solid and white substances.
- Ionic bonding involves the transfer of electrons between metals and non-metals.
Element Classes
- Potassium (K) is classified as a metal.
- Chlorine (Cl) is classified as a non-metal.
Behavior of Ionic Compounds in Water
- When ionic compounds dissolve in water, cations (positively charged ions) and anions (negatively charged ions) are released into the solution.
- An example of an ionic compound that conducts electricity in water is potassium chloride (KCl).
Charge of Ions
- Anions carry a negative charge, contributing to their net charge being considered as positive in contrast to cations which are positively charged.
Lewis Structure and Octet Rule
- The correct Lewis structure of carbon dioxide (CO2) includes double bonds between the carbon and each oxygen atom to fulfill the octet rule for carbon, allowing it to achieve a stable electron configuration.
