Study Notes
Paramagnetic Elements
- Paramagnetic elements have unpaired electrons
- They are attracted to an external magnetic field
Erwin Schrodinger
- Proposed the probability that electrons will be found in certain locations around the atom's nucleus
Electron Configuration
- Electron configuration is the distribution of electrons in various energy levels
- 3 energy level d sublevel = 3d
- Gallium (31) is in the 4th energy level and group 3
Chemical Bond
- Atoms react to form chemical bonds to become stable
- Ionic bond: Metal transfers electron to non-metal (e.g., sodium to fluorine)
- Covalent bond: Atoms share electrons (e.g., carbon to carbon)
Examples of Ionic and Covalent Compounds
- AlCl₃ (Aluminum Chloride) - Ionic
- CHâ‚„ (Methane) - Covalent
- MgBrâ‚‚ (Magnesium Bromide) - Ionic
- NaCl (Sodium Chloride) - Ionic
Helium (He)
- Helium's valence shell is full, preventing it from bonding with another He atom
Ionic Compounds
- Metal atoms lose electrons, forming positive ions
- Non-metal atoms gain electrons, forming negative ions
- Examples of naming compounds:
- Sodium Chloride (NaCl): Salt
- Sodium Bicarbonate (NaHCO₃): Baking Soda
- Aluminum Chloride (AlCl₃)
- Magnesium Oxide (MgO)
- Calcium Fluoride (CaFâ‚‚)
Carbon and Hydrocarbons
- Carbon atoms readily form many organic compounds due to its ability to form various bonds with other carbons.
- Hydrocarbons contain carbon and hydrogen.
- Alkanes, such as Ethane, contain only single carbon-carbon bonds.
- Alkynes, such as Ethyne, contain at least one carbon-carbon triple bonds.
