  3. Intramolecular force - Wikipedia

    en.wikipedia.org/wiki/Intramolecular_force

    Free atoms will have more energy than a bonded atom. This is because some energy is released during bond formation, allowing the entire system to achieve a lower energy state. The bond length, or the minimum separating distance between two atoms participating in bond formation, is determined by their repulsive and attractive forces along the ...

    An overarching aspect of mechanistic transition metal chemistry is the kinetic lability of the complex illustrated by the exchange of free and bound water in the prototypical complexes [M(H 2 O) 6] n+: [M(H 2 O) 6] n+ + 6 H 2 O* → [M(H 2 O*) 6] n+ + 6 H 2 O where H 2 O* denotes isotopically enriched water, e.g., H 2 17 O

    The book was also believed to be a source of inspiration to David Hahn, nicknamed "the Radioactive Boy Scout" by the media, who attempted to construct a nuclear reactor in his mother's shed, [2] although the book does not include any nuclear reactions. Due to safety concerns, the book was eventually pulled from library shelves. [3]

    Recognition status, as metalloids, of some elements in the p-block of the periodic table. Percentages are median appearance frequencies in the lists of metalloids. [n 2] The staircase-shaped line is a typical example of the arbitrary metal–nonmetal dividing line found on some periodic tables.

    [198]: 31 Reviews of the book indicated that the term "metalloids" was still endorsed by leading authorities, [199] but there were reservations about its appropriateness. While Berzelius' terminology gained significant acceptance, [ 200 ] it later faced criticism from some who found it counterintuitive, [ 197 ] misapplied, [ 201 ] or even invalid.
