Isomorphism (crystallography)

<h2 id="mitscherlichs-law">Mitscherlich's law</h2>
<p>Mitscherlich's law of isomorphism, or the law of isomorphism, is an <a href="/facts/Approximation/LvYHsXzq">approximate</a> <a href="/facts/Scientific_law/aVtc4wpk">law</a> suggesting that crystals composed of the same number of similar elements tend to demonstrate isomorphism.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>
</p><p>Mitscherlich's law is named for <a href="/facts/Germans/F7mBCrJ4">German</a> chemist <a href="/facts/Eilhard_Mitscherlich/19JYdzxm">Eilhard Mitscherlich</a>,<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> who formulated the law and published it between 1819 and 1823.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a>
</p><p>According to <a href="/facts/Ferenc_Szabadv%C3%A1ry/eaxGV0M6">Ferenc Szabadváry</a>, one of the clues that helped <a href="/facts/Berzelius/HakSv3sP">Berzelius</a> determine the atomic weights of the elements was "the discovery of Mitscherlich that compounds which contain the same number of atoms and have similar structures, exhibit similar crystal forms (isomorphism)."<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a>
