Lecture brief

Historical brief

Pauling and Allred–Rochow electronegativity, Kapustinskii lattice energy, CFSE and Goldschmidt radii organise the periodic solid. The sheets predict bond character and crystal packing. This sheet (INO-26 — Spin-only μ) is the form associated with spin-only. Working symbols: $n$ $\rightarrow$ $\mu$ . First-row ions.

Purpose

Purpose: compute

\mu

from

n

in Inorganic chemistry via

\\mu=\\sqrt{n(n+2)}

First-row ions. Use it when a real inorganic chemistry question must be answered in SI before a code check.

Live realistic example

In symbols

Live case. Given

n = 3.000\,\mathrm{—}

, the governing relation

\\mu=\\sqrt{n(n+2)}

yields

\mu = 3.87\,\mathrm{mu_B}

. First-row ions. Move a slider: the numbers are this situation, not a canned story.
