Its chemical composition contains helium-3, a heavier isotope of helium that exists naturally within the earth’s crust, but is now becoming exceedingly rare on our planet. WebCrystallization from Magma. Heat is energy that causes atoms in substances to vibrate. Temperature is a measure of the intensity of the vibration. If the vibrations are violent enough, chemical bonds are broken and the crystals melt releasing the ions into the melt. Magma is molten rock with freely moving ions.
