Study Notes
Electronic Configuration and Atomic Structure
- The electronic configuration of Cu⁺ ion: 3d¹⁰ 4s¹
- Atomic radius generally increases down a group in the periodic table; the correct order for Li, Na, B, Be is B, Be, Li, Na.
- The ground electronic state of Mn ion includes electron configurations: 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵.
Bonding and Molecular Interactions
- An n-bond results from the overlap of two p-orbitals.
- Alcohols form intermolecular hydrogen bonds, leading to increased boiling points and vapor pressure while enhancing solubility in polar solvents.
Reductive Properties of Halogens
- The correct order of halogen ions with decreasing reductive properties is I⁻, Br⁻, Cl⁻, F⁻.
Isotopic Composition
- Element X with atomic number 8 (Oxygen) and mass number 17 contains 8 protons and 9 neutrons.
- Since the atomic number equals the number of protons, element X has 8 electrons in a neutral state.
