Study Notes
Ionic vs. Covalent Bonds
- Ionic compounds involve the transfer of electrons from one atom to another, while covalent compounds involve the sharing of electrons between atoms.
- In covalent bonding, prefixes are used to indicate the number of each type of atom in the molecule.
Writing Covalent Compounds
- When writing the formula for a covalent molecule, incorporate appropriate prefixes to denote the quantity of each element involved.
- Avoid the criss-cross method for determining ratios in covalent compounds, which is typically used for ionic compounds.
Representation of Bonds
- To illustrate electron sharing in a covalent bond, visually represent the shared electrons by circling them around the respective atoms involved.
- For ionic bonds, depict electron transfer by drawing an arrow from the electron on the metal atom to the anion that requires the electron.
Common Molecular Compounds
- Carbon Dioxide is represented chemically as CO₂, meaning one carbon atom and two oxygen atoms.
- Water is chemically represented as H₂O, indicating two hydrogen atoms and one oxygen atom.
Prefix Usage in Covalent Compounds
- When adding a prefix to a compound where one of the elements begins with the letter "O", omit the "A" and "O" from the prefix for smoother pronunciation.
- The prefix "Deca" signifies the number ten in a molecular formula.
- The prefix "Mono" indicates one atom of a particular element in a compound.
