<p>as for <a href="page.php?w=Mercury_%28element%29">liquid mercury</a>, even at very high pressures (up to around 26 GPa), it contains many more atomic clusters with low <a href="page.php?w=Configuration_entropy">configurational entropy</a> than expected for a simple liquid.</p>

<p><big>Isotopes</big></p>
<p>Gallium has 30 known isotopes, ranging in <a href="page.php?w=mass_number">mass number</a> from 60 to 89. Only two isotopes are stable and occur naturally, gallium-69 and gallium-71. Gallium-69 is more abundant: it makes up about 60.1% of natural gallium,</p><p>
