Helium Helium Helium (from ) is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements. After hydrogen, helium is the second lightest and second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this figure in the Sun and in Jupiter. This
Stone boiling sources: the Database of North American Indians, Binford’s Hunter–Gatherer Database, and the eHRAF files. Access to the requisite fuels to heat stones is likely associated with stone boiling's use. For example, the Deg Hit'an and the Aleut used this cooking technique despite being above the 58-degrees latitude generalized threshold, which Harold E. Driver and William C. Massey attribute to their access to wood. Stone boiling Stone boiling is a moist-heat cooking method. It involves placing heated rocks into a water-filled container to heat the liquid to the point where it can be used to cook. This method of food preparation
