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.
